OPERATION

CAUTION! 

To prevent the workpiece or backup material from being 
torn from your hands while drilling, you MUST position the 
workpiece against the LEFT side of the column. If the 
workpiece or the backup material is not long enough to 
reach the column, clamp them to the table, or use a vise to 
brace the workpiece. Failure to secure the workpiece could 
result in personal injury. 
 
Use caution and slow feed rate down when drill bit is 
coming out bottom side of workpiece.  The drill bit can 
corkscrew the workpiece up and cause serious injury to the 
operator.  Therefore, work should be clamped down or held 
in a vice. 
 

DRILLING TO A SPECIFIC DEPTH  

Drilling a blind hole (not all the way through workpiece) to 
a given depth can be done two ways: 
 

Workpiece method (FIG. 20, 21) 

1.  Mark the depth (1) of the hole on the side of the 

workpiece. 

2.  With the switch “OFF”, bring the drill bit (2) down until 

the tip is even with the mark. 

3.  Hold the feed handle at this position. 
4.  Spin the lower nut (3) down to contact the depth stop lug 

(6) on the head. 

5.  Spin the upper nut (5) down and tighten against the lower 

nut (3). 

6.  The drill bit will now stop after traveling the distance 

marked on the workpiece.

Depth scale method (Fig. 21) 
Note:

 With the chuck at the uppermost position,  the tip of 

the drill bit must be just slightly above the top of the 
workpiece. 
 
1.  With the switch “OFF”, turn the feed handle until the 

pointer (7) points to the desired depth on the depth scale 
(4) and hold the feed handle in that position. 

2.  Spin the lower nut (3) down to contact the depth stop lug 

(6). 

3.  Spin the upper nut (5) against against the lower stop nut  

and tighten. 

4.  The drill bit will stop after traveling the distance selected 

on the depth scale.

REMOVING CHUCK (FIG. 22) 

1.  With the switch “OFF”, open the jaws of the chuck as 

wide as possible by turning the chuck counterclockwise. 

2.  Tap the chuck (1) lightly with a plastic tipped hammer at 

the top of chuck, until the chuck releases. 

NOTE:

 Place one hand below the chuck to catch it when it 

falls out.

CAUTION! 

To avoid injury from an accidental start, ALWAYS make sure the 
switch is in the “OFF” position, the switch key is removed, and the 
plug is not connected to the power source outlet before removing or 
installing the chuck.
