Metric/Fractional HSS 1/2” Reduced Shank Drill Sets Size:16mm - 25mm 4pce Metric 1/2” Reduced Shank Drill Set The right hand spiral forces

The right hand spiral forces the swarf out of the hole and prevents the chips from clogging at the bottom of the hole or in the flutes

particularly for non-ferrous applications

quick change adaptors and bit holders

In these situations it will produce thicker chips minimising work hardening of the cavity

Metric/Fractional HSS 1/2” Reduced Shank Drill Sets Size:16mm - 25mm 4pce Metric 1/2” Reduced Shank Drill Set The right hand spiral forcesReduced shank HSS twist drill set. 118 notched point with 30 helix. Notched point is a variation on the standard chisel point, providing faster starting and reduced drill wander. 118 point angles are ideal for use in materials such as mild steel and cast iron. The 118 point creates easily controlled chips which are wide and thin. Bordo reduced shank HSS drills are ground and then a black finish is achieved by steam tempering, a thermal process
