Foredom P-DP39 - Manual (Page 2)

GENERAL INFORMATION
The Foredom ® P-DP39 Drill Press is designed for use with the H.30 ® and H.44T
Handpieces. It securely holds the handpiece in a vertical position for drilling straight, accurate
holes to specified depths. It is ideal for drilling, modeling, spotfacing, countersinking and
reaming in wood, wax, plastic, metal, glass and gemstone. It can be used with any Foredom
flexible shaft power tool.
PLEASE FOLLOW THESE IMPORTANT SAFETY INSTRUCTIONS:
Always wear safety glasses to protect eyes from flying debris and chips.
Never continue to use a drill or accessory which appears to be wobbling, out of round,
vibrating or not running true.
Always use drills and accessories rated for 18,000 RPM or higher.
Never wear loose clothing, dangling jewelry or other apparel which may become caught
in the equipment.
Always keep hands, fingers and hair well away from the drill or other accessories.
Always bolt down the Drill Press for extra stability.
As you unpack the Drill Press, make sure that you have the complete P-DP39 assembly (see
illustration) and the allen wrench provided. Loosen the adjusting knob (24) and move the
head up the post (7) to the desired height. Tighten the knob securely. Be sure that the head,
table and base are aligned and centered. Foredom recommends bolting the drill press to the
workbench or platform for extra stability. Insert suitable length bolts through the four holes
provided in the base plate (9). Fasten to the workbench or to a piece of plywood
approximately 2′ x 2′ x 3/4″.
Arm Adjustment
Test the downstroke action of the handle. This has been preadjusted at the factory, but may
have rattled loose during shipping. It should feel smooth and free. If it feels too loose, adjust
the shoulder screws (26) in the handle arm assembly.These screws should be tightened snugly.
Inserting the Handpiece
Do not tighten the two socket cap screws (12) unless handpiece is inserted in holder. To insert
the handpiece, loosen the two socket cap screws with the allen wrench provided. Insert the
handpiece into the handpiece guides. When using the H.30
® Handpiece, make sure the chuck
key hole is facing forward and is accessible. If using the H.44T Handpiece, make sure that the
pin hole is accessible. Insert the handpiece through both guides until the tip of the collet or
chuck is approximately 1″ below the bottom guide. Tighten alternately the two socket cap
screws enough to prevent the handpiece from turning in the guides. Next, insert the drill or
accessory and tighten securely in the chuck or collet using the chuck key for the H.30
Handpiece and the pin and wrench for the H.44T.
Be sure to remove the pin from the handpiece hole of the H.44 T before starting the motor.
Table Adjustment
Determine the desired table height for the thickness of the material to be worked,
leaving approximately one inch between tip of drill and workpiece when placed on adjustable
table. When using a drill, make sure that the drill tip is aligned with the center of the table
drill hole by moving the drill gently through the hole while the motor is still off.

Table Drill Hole
Dial Indicator Installation and Adjustment
The Foredom P-DP39 is equipped with a dial indicator measurable in millimeters. (The tic
marks on the face of the large dial represent 1/100mm; small dial represents full millimeters.)
This feature allows an operator to have precise control of the vertical movement of the hand-
piece head assembly. Install the indicator by placing it into the hole in the indicator mounting
bracket (15), and tightening set screw (1).
Adjusting dial indicator to zero:
1. Place workpiece on adjustable table (10).
2. Lower the drill press head using handle (19) until the accessory or drill touches the
workpiece. Lock the head in place using head locking arm (18).
3. Loosen indicator mounting bracket using indicator mount locking knob (29) with your
right hand and holding mounting bracket (15) with your left hand.
4. Lower dial indicator assembly (15 & 13) until it touches datum (16), then compress
indicator plunger until small dial has rotated more than the hole depth desired (up to
25mm). Hold mounting bracket in place and retighten knob (29).
5. Turn outer ring of dial indicator until large needle meets the zero point.
6. Unlock the head by turning the head locking arm (18).
Drill Stroke Adjustment
This adjustment will allow you to return to the same specified depth for multiple drilling
strokes. Turn precision stroke adjustment knob (22) until the screw touches the black head
assembly (6). Reset large needle to zero point if necessary. Release head locking arm (18). To
adjust the drill stroke depth, move the head down to the desired depth as shown on the dial
indicator from zero point by pressing down on the handle or turning the precision stroke
adjustment knob (22) clockwise. Move locknuts (3) until they hold the head in this position.
(Unscrew the knob (22) enough to allow head to rise freely.)
Drilling
High speed steel, carbide and diamond drills are most often used. Whatever accessory you use,
let the speed of the tool do the work. Too much feeding pressure can damage or break your
drill, and may cause loss of control. When drilling, lift the drill up and down frequently to
clear away dust and chips.
Note: when using twist drills for drilling holes on work items with
rounded surfaces such as rods, it is a good idea to centerpunch a starting hole to keep the tip
of the drill from “walking” or wandering from the desired starting point.
Speed
Always use drills and accessories rated for 18,000 RPM or higher. Generally, work speed is
determined by experience and varies with the type of material being drilled or worked on, the
type of drill or accessory, the thickness of the material and the type of work being done.
Follow recommendations of the drill or accessory manufacturer. Usually, higher speeds are
used on soft materials and lower speeds on harder materials. It is always a good idea to
experiment on a scrap piece of material before beginning the final work operation.
Coolants
Coolants are sometimes needed to help keep the accessory cool and to keep the workpiece
clean of debris. Which type to use is determined by the material and the accessory and will
vary with operator preference. Wetting agents with rust inhibitors, waxes, oils and water are
often used when drilling extremely hard materials such as metals, gems and stones.
Lubrication
All unpainted surfaces are sprayed with a rust inhibitor when shipped. Be sure to clean away
all debris after use. Respray with rust inhibitor when necessary, especially during storage. The
spring and two shoulder screws (26) should be lubricated periodically with a light coat of oil.
