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.G REGRINDING • 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.H • Apply web thinning for the drill above ø6 mm. S-type thinning shown in figure at right is recommended. Preferable thinning width (W1) is about 1/2 to 1/3 of web thickness (W).
