• Drill Bit Diameter: 4.0mm
• Overall Length (OL): 75mm
• Working Length (WL): 43mm
• Material: High-Speed Steel (HSS)
• Coating: Titanium Nitride (TiN)

Compared to standard high-speed steel drill bits, this TiN coated version from IRWIN offers a noticeable upgrade in both longevity and cutting efficiency. The 4.0mm diameter provides versatility for tasks requiring precision, while the 75mm overall length and 43mm working length ensure improved reach and depth for a variety of applications. Many traditional drill bits can dull rapidly or suffer from poor heat dissipation; however, the TiN coating significantly extends cutting edge sharpness and reduces friction, outperforming many comparable options and previous models within the IRWIN range.

Key Technical Advantages:
Technology and Performance
