1.Integral cutting edges
remove the burr from the front of the hole as
the tool enters the hole.
2.The slotted design allows the tool to
'collapse' under load as the tool feeds through
the workpiece. The crowned and polished top
surface of the cutting edges will not mar the
inside surface of the hole.
3.The back of the hole is deburred on the retun
stroke.

Tool adjustment and operating recommendations
|
Fast and easy adjustment
The amount of edge break will vary with the hardness of
the
material.Loosen the screw on the sliding
tension-adjustment
mechanism and move it up or down the length of the slot
for
more or less stock removal.
Speed and feeds
As with burr off,use the same speed and fee rate as you
would
run a standard HSS drill.
Tool maintenance and edge resharpening
Regrinding Guidelines:To extend the life of the tool,the
cutting edges maybe regrinded up to four times.
Inspect for grit and foreign matter during and after
each operation.Clean as needed.
The burr off should be inspected periodically for grit
and foreign
particles,and cleaned as necessary.
The cutting edges may be reground up to four times in
order to
extend tool life.Refer to Figure 2 below for proper
regrind procedure. |
