Dormer Drill Bit HSS 7/16″

TiN-Tip Performance The Titanium Nitride coating on the tip increases surface hardness and reduces friction. This allows for significantly higher cutting speeds and a longer tool life compared to standard uncoated HSS bits.

Self-Centering Split Point Equipped with a 118° split point, the bit resists “walking” on the material surface. It provides an accurate start without the need for a pilot hole or center punch, even on hard or curved surfaces.

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

Broad Material Application Engineered for versatility, it performs exceptionally well in alloyed and non-alloyed steels, cast iron, and non-ferrous materials like aluminum or copper.

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.

Precision Standards Manufactured to ANSI specifications, ensuring strict diameter tolerances for critical mechanical fits and industrial assembly.
