Dormer Drill Bit HSS 9/32″

High-Hardness TiN-Tip The Titanium Nitride coating at the point reduces friction and dissipates heat. This allows for significantly higher cutting speeds and a service life up to three times longer than standard uncoated bits.

Self-Centering Split Point Equipped with a 118° split point geometry, the bit bites into the material instantly. This prevents “wandering” and eliminates the need for a center punch, ensuring accurate hole placement.

Superior Chip Evacuation The specialized flute design is engineered to lift and remove swarf rapidly. This prevents clogging, reduces heat buildup, and ensures a cleaner finish inside the hole.

Industrial-Grade Versatility Engineered to perform exceptionally well across a wide variety of materials, including alloyed and non-alloyed steels, cast iron, and non-ferrous metals.

Steam Tempered Finish The body features a steam-tempered (blue) finish that improves the retention of cutting fluids, keeping the bit lubricated and extending the life of the cutting edge.

Standard Compatibility With a diameter of 7.14mm, this bit fits easily into all standard 10mm (3/8″) and 13mm (1/2″) drill chucks.
