Drill Bit A Forged Tool 09083805 8mm Steel

The ALPEN Drill Bit A Forged Tool 09083805 8mm Steel is a high-quality HSS spiral drill bit designed for precision drilling across a range of materials. With an 8 mm diameter and forged construction in high-speed steel, this tool is intended to provide reliable drilling performance for both professional trades and home workshop tasks. The geometry and sharpening of the bit support efficient cutting and extended service life under typical drilling conditions.

Advantages

This 8 mm HSS drill bit offers improved drilling speed and longer tool life compared with standard bits thanks to optimized geometry and high-quality heat-treated steel. Its forged construction provides increased elasticity and resistance to breakage during hand-held or machine drilling. The bit’s design promotes stable cutting and consistent hole quality in a variety of materials, supporting repeated use with reduced wear.

Suitable for

• Drilling alloy and non-alloy steels
• General metalworking tasks in workshops and maintenance
• DIY projects requiring precise 8 mm holes
• Hand-held drilling and machine drilling applications

Key specifications

• Material: High-speed steel (HSS), heat treated
• Diameter: 8 mm
• Spiral geometry: universal spiral for enhanced cutting
• Construction: forged bit for increased elasticity and strength
• Intended use: metal drilling, including alloy and non-alloy steels

How to use

Select the 8 mm ALPEN HSS drill bit for the intended material and secure the workpiece. Use an appropriate drill speed for HSS bits and apply steady, moderate feed pressure. For hand-held drilling, maintain alignment and reduce side loads to minimize breakage. For thicker or harder steels, use intermittent drilling with coolant or cutting fluid to control heat and extend tool life. Replace the bit when wear increases or hole quality declines.

Usage recommendations

Use cutting fluid on hard or thick materials, start at lower speed when centring, and ensure the chuck holds the 8 mm shank securely. Store the bit dry and protected to preserve the heat-treated cutting edges and prevent corrosion.
