CAUTIONARY NOTES

To prevent edge chipping, hone cutting edges as follows: Honing width: 0.02 ~ 0.05 mm Honing angle: -20˚ to -30˚. G Chipping is likely to occur on edges whilst drilling hard materials, a larger honing width is recommended.
When drilling into an inclined surface, special care should be taken to prevent drill breakage.

Use of drill bushing is recommended for such case.

REGRINDING H

Carry out regrinding when corner wear reaches the margin width.
Avoid using silicon carbide grinding wheels or hand grinding whenever possible.

Use diamond grinding wheels of 200 to 400 mesh.

Apply web thinning for the drill above ø6 mm. S-type thinning shown in ﬁ gure at right is recommended.

Preferable thinning width (W1) is about 1/2 to 1/3 of web thickness (W).		I
