Drill bit set Bosch 2608664677 — 5-piece HSS drill bits

Bosch 2608664677 — 5-piece HSS drill bits is a compact set of high-speed steel bits intended for general-purpose drilling in metal and wood. The set contains five commonly used diameters and is compatible with standard drill chucks, providing a straightforward solution for workshop tasks, maintenance and DIY projects that require reliable hole-making performance.

Advantages

The HSS construction delivers wear resistance and consistent cutting performance across repeated use. Precision-ground flutes and a standard point angle ensure accurate centring and smooth chip evacuation when drilling into a range of materials. The compact 5-piece composition keeps common sizes on hand, reducing the need to change bits frequently during routine tasks.

Suitable for

• Drilling holes in mild steel and other ferrous metals
• Woodworking and timber drilling for assembly and fittings
• General workshop maintenance and repair
• Home DIY projects requiring standard bit sizes
• Use with corded and cordless drills that accept standard chucks

Key specifications

• Material: High-speed steel (HSS) for durability during metal and wood drilling
• Pack size: 5 drill bits covering common diameters for general use
• Compatibility: Fits standard three-jaw and keyed drill chucks
• Design features: Precision-ground flutes and conventional twist-drill geometry for efficient chip removal
• Intended applications: Metalworking and woodworking hole-making tasks

How to use

Select the appropriate drill bit diameter from the set for the required hole. Secure the drill bit in the drill chuck, ensuring it is tightened and centred to avoid wobble. When drilling metal, use a suitable cutting lubricant and apply steady pressure at the correct speed for the material; for wood, use moderate speed and firm control to prevent splintering. Retract periodically to clear chips and maintain bit temperature for longer tool life.

Usage recommendations

For best results, match drill speed and feed to the material: lower speeds and cutting fluid for harder metals, higher speeds for softer metals and wood. Store bits in their case or a dedicated holder to protect the cutting edges and check bits for wear before use to maintain accuracy and safety.
