## Summary description

Irwin IR HSS PRO TIN DIN 338 7.0 mm is a high-speed steel drill bit with titanium nitride (TiN) coating, designed to DIN 338 standards. The 7.0 mm diameter and straight/cylindrical shank suit general-purpose drilling in metal and other materials. TiN coating increases wear resistance and tool life. Use in handheld or machine drills for precise, durable drilling.

## Long description

Irwin IR HSS PRO TIN DIN 338 7.0 mm is a high-speed steel (HSS) twist drill designed to DIN 338 standards with a 7.0 mm cutting diameter and a straight (cylindrical) shank. The tool features a titanium nitride (TiN) coating applied to the flutes and cutting edges to improve wear resistance and extend tool life. Intended for general-purpose drilling in metal and a range of other materials, this drill bit can be used in handheld and machine drills for accurate, repeatable holes.
Advantages
The TiN coating reduces friction and increases hardness on the cutting surfaces, which helps maintain sharpness for longer and improves drilling speed and consistency. The HSS substrate provides toughness and heat resistance appropriate for metalworking, while the DIN 338 geometry offers a reliable flute shape and point angle for efficient chip evacuation and centring. The straight shank allows stable clamping in standard chucks and is compatible with common drill holders.
Suitable for
Drilling holes in ferrous metals such as mild steel and alloy steel
Working with non-ferrous metals like aluminium and brass
General-purpose workshop tasks and maintenance drilling
Use in handheld drills and drill presses for fabrication and repair
Key specifications
Material: high-speed steel (HSS)
Coating: titanium nitride (TiN)
Diameter: 7.0 mm
Shank type: straight / cylindrical
Standard: DIN 338 geometry
Typical applications: metalworking, general-purpose drilling
How to use
Mount the drill bit securely in a keyed or keyless chuck ensuring the shank is fully seated and clamped. Select an appropriate spindle speed and feed rate for the material being drilled; use lower speeds for hard or thick metals and higher speeds for softer materials. Apply steady, even pressure and allow the drill to cut without excessive force. Use lubricant or cutting fluid when drilling metals to reduce heat buildup and improve chip evacuation. Withdraw the bit periodically to clear chips when drilling deeper holes.
Usage recommendations
For best results when drilling metals, use suitable cutting fluid, moderate cutting speeds, and steady feed. Inspect the TiN coating and cutting edge before use and replace the drill when wear or bluntness affects hole quality. Avoid excessive lateral force to prevent chipping or breakage of the HSS tip.
