Precision IRWIN metal drill bit with titanium nitride (TiN) coating, 1.5 mm diameter, offers long service life, fast chip evacuation, and stable centering thanks to a 135° tip. Ideal for rotary metal drilling, supplied as a set of 2.
Professional IRWIN HSS TiN drill bits in 1.5 × 18 / 40 mm are designed for precise drilling in metals. The TiN coating significantly increases wear and heat resistance, delivering up to 6× longer life compared to standard HSS bits with a black oxide finish. The ground 135° tip ensures easy centering and requires less drilling pressure, reducing the risk of slippage.
The optimized industrial-grade flute supports rapid chip removal, smooth operation, and clean holes. Thanks to the TiN coating’s low friction coefficient, you can increase spindle speed by 40–60% and feed rate by 10–20% without a significant reduction in tool life. The lower thermal conductivity of TiN also transfers more heat into the chips and coolant, protecting the drill bit itself.
- High TiN coating hardness ~80 HRC for maximum durability
- Cylindrical shank for universal clamping in standard chucks
- Rotary drilling method for precise and efficient results
- Set of 2 – value pack for workshop and home use
