Broca helicoidal 16 mm HSSE-Co5 con recubrimiento TiN DIN 338 para acero inoxidable, longitud de trabajo 120 mm, longitud total 178 mm

Machinists and metal fabrication professionals rely on this 16 mm twist drill bit when working with stainless steel and high-alloy steels. Its HSSE-Co5 construction with 5% cobalt delivers superior heat resistance, while the TiN coating reduces friction and extends tool life. The fully ground flutes ensure precise holes and efficient chip evacuation in demanding industrial applications.

Key specifications

• Drill bit type: Twist drill bit
• Diameter: 16.00 mm
• Working length: 120 mm
• Overall length: 178 mm
• Material: HSSE-Co5 (5% cobalt high-speed steel)
• Coating: Titanium Nitride (TiN)
• Standard: DIN 338
• Shank: Cylindrical
• Cutting direction: Right-hand
• Point angle: 135° split point
• Suitable for: Stainless steel (INOX), high-alloy steel, heat-resistant steel, cast iron

Why choose it

The cobalt-enriched HSSE steel maintains hardness even at high temperatures, preventing premature wear when drilling tough alloys. The TiN coating lowers friction, reduces heat buildup, and improves chip flow, resulting in cleaner holes and longer service life. The 135° split point starts on contact without walking, eliminating the need for center punching.

Ideal use cases

• Drilling stainless steel components in metalworking shops
• Creating precise holes in high-alloy steel for machinery
• Maintenance and repair tasks on heat-resistant steel parts
• Production drilling in cast iron workpieces

Good to know

For best results, use cutting fluid and appropriate speeds for stainless steel. The cylindrical shank fits standard drill chucks. This bit is fully ground from solid stock, ensuring consistent geometry and performance. It is a single piece, ideal for professional and industrial use.
