Poranterä Bosch 2608833892, 8 mm halkaisija, sylinterimäinen varsi

Bosch 8 mm drill bit model 2608833892 is a straight-shank twist bit designed for general-purpose drilling where an 8 mm hole is required. The bit is intended for use with standard hand drills and drill drivers that accept straight shanks. Its geometry and diameter suit routine tasks such as furniture assembly, light construction work and maintenance, providing predictable hole size and compatibility with common chuck types.

Advantages

The straight shank enables secure clamping in most three-jaw chucks and keyless chucks, reducing slippage during use. The 8 mm diameter yields consistent hole sizing for dowels, fasteners and passages for cables or pipes. Manufactured by a recognized tool brand, the bit benefits from controlled manufacturing tolerances that support repeatable drilling performance and straightforward interchangeability with other standard bits.

Suitable for

• Drilling 8 mm holes in wood and wood-based panels
• Furniture assembly and dowel installations
• Light construction and repair tasks
• General maintenance where a standard straight-shank bit is required

Key specifications

• Shank type: straight shank, compatible with standard drill chucks
• Diameter: 8 mm
• Bit style: twist drill geometry for general-purpose drilling
• Material and heat treatment: manufacturing-grade tool steel appropriate for typical drilling loads
• Intended drive: hand drills and drill drivers with compatible chuck capacity

How to use

Fit the 8 mm straight shank into the drill chuck and tighten securely before operation. Select a suitable rotational speed for the material being drilled — lower speeds for dense materials, higher speeds for softwoods. Apply steady axial pressure and allow the bit to cut without forcing; periodically withdraw the bit to clear chips when drilling deep holes. Use appropriate personal protective equipment such as safety glasses and hearing protection as needed.

Recommendations

To prolong bit life and maintain hole accuracy, avoid excessive side loading and over-speeding. When drilling metals or abrasive materials, consider using cutting lubricant, reduced speed and intermittent cutting to manage heat and wear.
