Dormer Drill Bit HSS 1/2″

TiN-Tip Coating The Titanium Nitride coating at the point reduces friction and dissipates heat, allowing for increased cutting speeds and a service life significantly longer than standard HSS bits.

Self-Centering Split Point Features a 118° split point geometry, which ensures the bit starts exactly where it is placed without “walking” or “wandering,” even on curved surfaces.

Optimized Flute Geometry The “parabolic” flute design provides superior chip evacuation, which is critical for a 1/2″ diameter bit to prevent clogging and overheating during deep-hole drilling.

Industrial-Grade Versatility Specifically designed to drill through a wide range of materials, including alloy and non-alloy steels, stainless steel (limited), cast iron, and aluminum.

High Precision Manufactured to meet ANSI standards, ensuring the hole diameter is consistent and accurate for critical mechanical tolerances.

Steam Tempered Body While the tip is TiN-coated, the body is steam-tempered (blue finish) to retain cutting fluid more effectively, further reducing wear and tear.
