## Summary description

Irwin IR HSS PRO TIN DIN 338 8.0 mm is a high-speed steel (HSS) drill bit with a titanium nitride (TiN) coating, manufactured to DIN 338 dimensions. Designed for drilling metal and other materials compatible with HSS bits, it delivers improved wear resistance and longer life compared to uncoated bits. Suitable for workshop and professional use where precision and durability are required.

## Long description

Irwin IR HSS PRO TIN DIN 338 8.0 mm is a high-speed steel (HSS) twist drill manufactured to DIN 338 dimensions and finished with a titanium nitride (TiN) coating. The 8.0 mm diameter bit is designed for general-purpose metalworking and for drilling into materials suitable for HSS tools. The TiN coating increases surface hardness and reduces friction for improved wear resistance compared with untreated HSS drills, while the DIN 338 geometry supports stable centring and consistent chip evacuation.
Advantages
The TiN coating extends tool life and helps maintain cutting performance under continuous use. Precision ground flutes and tip geometry consistent with DIN 338 deliver reliable hole accuracy and repeatability. The bit provides good heat resistance during standard drilling speeds and is suitable for use with cutting fluid to enhance life and finish. Compatibility with common drilling chucks and holders makes it a practical choice for workshop and professional environments.
Suitable for
 Drilling through mild steel and other ferrous metals compatible with HSS drills
 General metal fabrication and maintenance work
 Workshop use in hand-held or bench drills
 Prototype and repetitive drilling where consistent hole diameter is required
Key specifications
 Material: High-speed steel (HSS)
 Coating: Titanium nitride (TiN)
 Shank type: Cylindrical (standard drill shank)
 Tip/geometry: DIN 338 twist drill profile
 Diameter: 8.0 mm
 Application: Designed for drilling metal and materials suitable for HSS
How to use
Select the 8.0 mm Irwin HSS PRO TIN drill bit and secure it in the drill chuck, ensuring concentric mounting. Mark and, if necessary, center-punch the drilling point to reduce walking. Use recommended drilling speeds and appropriate feed pressure for HSS into the specific material being worked; reduce speed for harder materials. Apply cutting fluid when drilling metal to reduce heat buildup and prolong tool life. Clear chips regularly and allow the bit to cool between long cycles to avoid tempering and loss of hardness.
Usage recommendations
For best results, use the TiN-coated HSS bit at moderate speeds with light to moderate feed and apply cutting fluid when drilling steels. Re-sharpening is possible on conventional tool grinders if wear occurs; replace the bit when wear compromises hole accuracy or when chipping appears on the cutting edges.
