Dormer Drill Bit HSS 5/16″

High-Performance TiN-Tip 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.

No-Wander Split Point Equipped with a 118° split point geometry, this bit is self-centering. It bites into the material immediately upon contact, eliminating the need for a center punch.

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 Specifically designed to drill through a wide range of materials, including alloy and non-alloy steels, cast iron, and non-ferrous metals like aluminum.

Steam Tempered Finish The body features a steam-tempered (blue) finish that improves the retention of cutting fluids, ensuring the bit stays lubricated and cool during heavy-duty tasks.

Universal Compatibility With a diameter of 7.94mm, this bit fits perfectly into all standard 10mm (3/8″) and 13mm (1/2″) drill chucks.
