14. DRILL PRESS, FLOOR STANDING (General International 75-500M1, Central Machinery T-

583, Jet JDP-17MF) & BENCH STANDING (Delta 11-950)

(NOTE: Portions of the information presented in this section were taken from the General

International Operating Manual.)

We have four drill presses in the shop, one General International 22” floor standing, two Central

Machinery 16” floor standing and one 8” bench standing. Only one unit is presented herein, as the

principles and the general operation and adjustments are similar for all four.

With a drill press:

• You can preset the depth of your hole and consistently cut numerous holes

at the same depth.

• You can use Forstner bits, spade bits and hole saws to smoothly and safely

bore wider diameter holes.

• With a floor or bench standing drill press and a long bit, you can bore out

very deep holes that would be impossible to get straight with a hand-held

power drill.

14.1. Safety Precautions

a. NEVER START THE MACHINE BEFORE CLEARING THE TABLE OF ALL OBJECTS (tools, scrap pieces,

etc.). Debris can be thrown at high speed.

b. TIGHTEN ALL LOCK HANDLES before starting the machine. Loss of control of the workpiece can

cause serious injury.

c. AVOID AWKWARD OPERATIONS AND HAND POSITIONS. A sudden slip could cause a hand to

move into the bit.

d. PROPERLY SUPPORT LONG OR WIDE workpieces. Loss of control of the workpiece can cause

severe injury.

e. NEVER PERFORM LAYOUT, ASSEMBLY OR SET-UP WORK on the table/work area when the

machine is running. Serious injury can result.

f. HOLD material to be drilled securely; it is best to use a vise or a clamp.

g. MAKE SURE drill bit or cutting tool is securely locked in the chuck. Remove chuck key from the

chuck.

h. MAKE SURE that you remove the chuck key before starting drill press.
