Drill bit Bosch 8 mm HSS 2608833788 for metal and wood

Bosch 8 mm HSS drill bit 2608833788 is a high-speed steel tool intended for general-purpose drilling in metal and wood. It is engineered to deliver stable cutting performance and wear resistance for both manual and machine drilling. The bit produces accurate 8 mm holes in thin to medium thickness materials and is suitable for workshop and construction environments where consistent hole diameter and reliable penetration are required.

Advantages

The HSS construction provides good hardness and heat resistance for sustained drilling in metal and wood. A precisely ground tip and flute geometry ensure stable chip evacuation and reduced walking at start, improving hole accuracy. The solid shank design fits standard chucks and enables use with hand drills and drill presses. The bit's dimensions and material composition offer a balance between toughness and cutting performance for everyday drilling tasks.

Suitable for

• Drilling holes in mild and alloy steels, sheet metal and pipes
• Drilling in soft and hardwoods for fittings and joinery
• Workshop maintenance and on-site construction tasks
• Use with hand-held drills and drill presses for general fabrication

Key specifications

• Drill diameter: 8 mm
• Material: high-speed steel (HSS)
• Intended materials: metal and wood
• Shank type: straight round shank for standard chucks
• Tip geometry: ground tip for improved centring
• Typical applications: general-purpose metalworking and woodworking

How to use

Secure the workpiece and select an appropriate drill speed for the material: lower speeds for metal and higher speeds for wood. Clamp the 8 mm HSS drill bit in the drill chuck ensuring it is tight and concentric. For metal, apply cutting fluid or coolant to reduce heat and improve tool life; for wood, no coolant is required. Start drilling with light pressure to establish the hole, then increase steady feed while maintaining alignment. Withdraw the bit periodically when drilling thicker metal to clear chips and prevent overheating.

Recommendations

Use protective eyewear and gloves during operation. For extended metal drilling, refrigerate with cutting oil and avoid excessive feed rates to prevent premature wear. Replace the drill bit when accuracy degrades or after visible wear to maintain hole quality.
