Drill Bit A Forged Tool ALPEN 09083800 8mm HSS Co 5%

ALPEN Sprint Master HSS drill bit set in a compact case, containing six sizes (2.0, 3.0, 4.0, 5.0, 6.0 and 8.0 mm). These spiral bits are made for hand drilling and are suitable for alloy and non-alloy steel. The Sprint Master design combines optimized geometry, special sharpening and high-quality HSS material to deliver faster drilling and extended tool life.

Advantages

The Sprint Master series offers up to 30% faster drilling thanks to its optimized geometry and special sharpening. Heat-treated high-speed steel with enhanced composition increases service life (noted as up to twice as long in the source) and improves resistance to breakage through higher elasticity. The bits provide consistent drilling quality and optimal cutting performance for a range of metalworking tasks.

Suitable for

• Hand drilling in alloy and non-alloy steel
• General metalworking and workshop tasks
• Drilling where high elasticity and reduced breakage risk are required

Key specifications

• Set contents: 6 pieces — diameters 2.0, 3.0, 4.0, 5.0, 6.0, 8.0 mm
• Material: High-speed steel (HSS) with heat treatment; source notes HSS Co 5% for related product data
• Design features: Optimized geometry and special sharpening for faster drilling
• Packing: Blister pack (noted as blister pack with 3 pieces in source; set supplied in case with 6 pieces)

How to use

Select the appropriate diameter for the hole required and secure the workpiece. Install the Sprint Master bit in the drill chuck and tighten firmly. Use suitable cutting speeds and moderate feed pressure for steel; apply cutting fluid when drilling harder alloys to reduce heat and extend bit life. Start drilling at low speed to establish the hole, then increase speed as appropriate for material and bit size.

Usage recommendations

For best results, use proper coolant when drilling alloy or hard steels, maintain stable clamping of the workpiece, and replace worn bits to preserve hole quality and reduce risk of breakage.
