Your Source for Automatic Drills, Multiple Spindle Heads, and more

Just Automatic Drills

AutoDrill drilling and tapping products have been at the forefront of automated production for many years. AutoDrill drills provide versatile and cost-effective, customized solutions for dedicated drilling and tapping stations that turn out more precision parts in less time.

Larger Automatic Drills

These automatic drills can tap as well as drill. The tap tooling automatically reverses for withdrawal on our standard and control feed tapper units. This system requires no mechanical parts other than the highly reliable and industrial rated self-reversing tapping head.

Our automatic drills are capable of drilling a variety of hole sizes. All AutoDrill autofeed drill units feature low air consumption requirements unless pneumatic motors are used. This makes them extremely environmentally friendly or “green” as they say.

These units can handle up to 5 HP and produce well over 1000 lbs. of thrust from most shop air systems.

The Series 2000 AutoDrill is an air controlled self-feed drill. It is the most versatile automatic drill machine in AutoDrill’s our up. The self contained hydraulic feed control (sometimes called Hydro Feed or Hydro-Brake) is useful when a clean hole breakthrough is desired. It also improves hole roundness in thin sections, control when drilling smaller hole sizes, managing the Horsepower requirement on larger hole processes or when two-speed operation is desired. We also offer SkipFeed and PeckFeed options for the 2000 series units.

You can click below for more information on the self feed AutoDrill 2000 series options.

Smaller Automatic Drills

The Series 1000 and 1100 automatic drill unit is a slim compact unit designed to cut operating costs while providing a wide range of capabilities. The small size of the AutoDrill automatic drill lets you adapt it readily to compact set-ups for close-center drilling. The drills are powered by either small electric (1 ph, 3 ph or DC) motors or air / pneumatic motors to increase the drills flexibility. There are no pulleys or gears to change and the unit is mounted much the same way a typical air cylinder is so it can be removed and remounted to the precise former location quickly and easily with the use of simple dowel pin locators. Although it is compact, the automatic drilling machine delivers maximum drilling capacity with 100 lbs thrust at 100 psi air pressure and a full 1-1/2″ inch stroke. These are the smallest production rated automatic drills on the market as far as we know.

Drill Unit and Self Feeding Drill Glossary of Terms

Actuator
A mechanical device capable of producing motion, i.e. AutoDrill’s Drill Unit has capability of both linear and rotary motion.
Air
Term loosely used to represent compressed air sources for use in manufacturing.
Ambient
The temperature and atmospheric conditions in the process area.

Clean Room

Applications characterized by the common requirement to minimize outside contamination. These type applications limit the use of lubricants and coolants or use lubricants and coolants that are safe for consumption, etc. Special materials and seal materials are often necessary to meet these requirements. Many medical and pharmaceutical applications require clean room features.
Collet
A tool holding device designed for maximum holding capacity and high accuracy. Each tooling size requires a separate collet.
Compressed Air
Industrial process air available for control and process uses at roughly 30 to 150 PSI but sometimes lower or higher depending on the application.
Counterbore (counter-bore)
The larger diameter at the entrance of a drilled hole with a flat bottom. Similar to a countersink except for the bottom configuration.
Countersink (counter-sink)
The larger diameter at the entrance of a machined hole with a conical bottom. Similar to a counterbore except for the bottom configuration. The general use of a countersink is for use with flat head screws and bolts.
Deep-Hole Drilling
Arbitrarily set at a depth to hole diameter ratio of 8:1 or greater. The torque required is generally more than shallow depth drilling and frequent tool retraction may be necessary to keep the flutes open. This tool retraction is known as peck drilling or PeckFeed.
DRAP (drill-tap)
A combination drill and tap that performs both operations in one sequence. It is useful for applications where the drilling and tapping settings are similar. The operation must be on a thru-hole part since the drilling must be finished before the tapping operation begins. Call for more information.
Drill Unit
A self-feeding drill module that is designed to automate multiple hole production drilling and other rotary/linear applications.
Double Feed Control
The ability to control the feed rate for both the extension and retraction portions of the drilling cycle.
Extended Rear Spindle
Additional length added to a Drill Unit spindle to allow the input of liquid or gaseous media thru the center of the spindle. The additional length is usually required to connect a rotary union to the spindle. The extended spindle can also be useful in situations where you need to attach something to the rear of the unit for various reasons. Some machine builders working directly with AutoDrill have manufactured Lead Screw Tap Tappers for our customers.
Feed
The linear extension towards the work of a Drill Unit quill.
Feed Control
The method to control the drill extension towards/into the work. The simplest but least precise method is pneumatic control. Another method is hydraulic feed control, which has a more accurate feed rate because of the incompressibility of oil.(i.e. oil does not compress under pressure)
Flow Control
A precision adjustable valve used to control the flow of a gaseous or liquid media.
FPR
Abbreviation for Feed Per Revolution, a term used in drilling applications to determine how fast the drill will go thru the material per revolution of the cutting tool. It is a major factor in determining the horsepower requirements for an application.
Gun Drilling – See Deep-Hole Drilling
Jacobs Taper
A standard shaft configuration that allows attachment of tool holders with minimal runout. Standard Jacobs Taper sizes are J0, J1, J2, J3, J33, J4, J5, J6
Multiple Spindle Head (Multi-Drill, Gang Drill, Spindle Multiplier)
A Drill Unit attachment with multiple drill or tap spindles where the spindles are gear driven from the Drill Unit spindle. They allow drilling or tapping of multiple holes in closer proximity than is possible with Drill Units alone. These devices can be mounted onto automatic drill units, drill presses, column drills, pillar drills, milling machines, CNC platforms, direct motor mounts and many other platforms.
PSI
Pounds per Square Inch, a measure of the energy stored in industrial compressed air or any other energy force.
Parabolic Drill
Drill designed for deep-hole drilling with good chip evacuation.
Peck Drilling
A technique where the tool is frequently retracted from the hole to clear drill chips and prevent clogging. It’s also used to help drill straight precision holes. Generally used when the hole depth is considered to be a deep-hole.
Quill
The linear guided, non-rotating portion of a Drill Unit or drill press. Its purpose is to securely support the rotating spindle. It is also often used to secure a multiple spindle head.
Rotary Union
A mechanical device that allows the transfer of a medium (air, water, other coolant, lubricant, etc.) from a stationary source to a rotating component.
Runout (run out, run-out)
The deviation from the desired surface or line in relation to the axis during one complete revolution.
Self-Contained
A Drill Unit that includes the ability to turn and extend in a compact package.
Self-Feeding (selffeeder, selffeeding, self-feeding)
The capability to automatically extend a drilling, tapping, reaming (etc.) device towards the work. The ability to automate a drilling (etc.) process.
Skip Feed Control
A control valve option available on AutoDrill series 2000 and 5000 Drill Units that allows multiple uncontrolled and controlled sections of the feed cycle. The valve essentially “skips” the feed control at desired portions of the feed cycle. Available in custom fixed models or even fully adjustable models, this device significantly speeds up the cycle time when drilling hollow pipe, tube, extrusions, etc.
Spindle
The high precision shaft that rotates within the quill and is the attachment point for the tooling or tool holder.
Spline Bushing
The part of a Drill Unit that transfers power from the input shaft or device to the spindle.
Thru-holes (through holes)
The hole drilled thru the spindle center (through spindle) to facilitate the introduction of coolant, lubricants, air or other media to the work area. It is also useful for the introduction of a work or slug ejector pin.
Thrust
When used as a drilling parameter it is the exertion forces of a tool into the work transmitted by the Drill Unit.
TIR
Total Indicator Reading is the total movement of a dial indicator for the deviation of a surface from it’s theoretical perfect dimension. In drilling, it is an indication of the deviation of the cutting tool’s centerline axis from it’s theoretical true centerline. (center line)
Two-Hand Anti-Tie-Down (Two Hand Anti-Tiedown)
A safety arrangement suited for machinery where position of an operator’s hands must be monitored. Operator must actuate both push buttons simultaneously to obtain an output signal and thus start a potentially dangerous equipment process.
