Micro 100 SPD-250-090 Spotting Drill Bit Carbide 90°

90° Carbide Spotting Drill Bit

The Micro 100 SPD-250-090 is a spotting drill bit made from C2 micrograin carbide with a 90-degree point angle. It is designed for machinists and fabricators who need a precise starter hole to prevent drill wander on hard materials. The bright, uncoated finish suits general-purpose spotting operations in a workshop environment. This accessory fits standard drill holders used in milling and drilling setups.

Build integration and clearance

The bit mounts directly into a compatible drill chuck or tool holder without additional adapters. Its rigid carbide construction reduces deflection, freeing the operator from frequent re-centring when starting deep holes. The 90-degree profile matches common chamfer angles, letting one tool handle both spotting and light chamfering tasks. Buyers needing coated tooling or different point angles for specialised alloys should evaluate other options.
