Drill bit Bosch 8 mm HSS 2608833786 for metal and wood

Bosch 8 mm HSS drill bit 2608833786 is designed for drilling precise 8 mm holes in metal and general-purpose materials. Manufactured from high-speed steel (HSS), the bit provides improved wear resistance and higher heat tolerance compared to standard carbon-steel bits. Its geometry and cutting edges are suitable for use with handheld and bench drills in workshop, repair and light construction environments where reliable, repeatable holes are required.

Advantages

The HSS material ensures durability and resistance to softening at elevated temperatures during continuous drilling. A precisely ground tip and flute design contribute to stable drilling performance, efficient chip removal and reduced walking on the workpiece. The 8 mm diameter offers a common size for fastener and dowel installations, while compatibility with standard drill chucks makes the bit easy to install and replace.

Suitable for

• Drilling holes in mild and alloy steels
• Through-holes in non-ferrous metals such as aluminum and brass
• General workshop and maintenance drilling tasks
• Woodworking tasks requiring 8 mm holes
• Use with handheld and bench drilling machines

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 8 mm
• Intended materials: metal and general-purpose materials including wood and non-ferrous metals
• Tip style: split and ground for reduced walking and improved centring
• Shank type: round shank compatible with standard chucks
• Typical applications: workshop, repair, construction and maintenance

How to use

Secure the drill bit in the drill chuck and tighten firmly. Select appropriate spindle speed for the material: lower speeds for harder metals, higher speeds for softer metals and wood. Apply steady axial pressure and allow the drill to do the work; avoid excessive force that can shorten tool life. Use cutting fluid or coolant when drilling steel to reduce heat and extend bit life. Clear chips regularly to maintain efficient cutting and prevent clogging.

Usage recommendations

For best results, start with a small pilot mark or pilot drill when high positional accuracy is required. When drilling metals, use a suitable cutting lubricant and moderate speed to preserve the HSS cutting edge; for wood and soft materials, higher speed and minimal lubrication are appropriate. Inspect the bit regularly for wear and replace when the cutting edges become rounded or performance drops.
