Dormer Drill Bit HSS Set 25Pcs.No.204 1-13mm

Enhanced Tool Life – The Titanium Nitride (TiN) coating on the tip increases surface hardness and lowers friction, allowing the bits to last significantly longer than standard HSS bits.

Comprehensive Metric Range – With 25 pieces covering every 0.5mm step up to 13mm, this set eliminates the gap in your toolkit for almost any standard metric drilling task.

Precision Starting – Equipped with a 118° split point, these bits are self-centering. This reduces the thrust force required and prevents the bit from “skating” on hard surfaces.

High-Speed Performance – The TiN-Tip allows for increased cutting speeds without sacrificing the structural integrity of the bit, making it ideal for high-production environments.

Versatile Material Application – Engineered to drill through a wide array of materials, including alloy steel, carbon steel, grey cast iron, and non-ferrous metals.

Rugged Storage Solution – Supplied in a heavy-duty, fold-out plastic index case. The bits stay organized and upright for quick size identification and easy selection.

Industrial Standard – Manufactured to DIN 338 specifications, ensuring consistent high-quality geometry and flute precision for clean, accurate holes.
