Carbide-tipped drill bit Bosch 2608900359, 5 mm diameter, straight shank is designed for precision drilling in a range of common construction materials when used with compatible drills. The 5 mm cutting diameter provides a clean, accurate hole size for assembly, fastening and general workshop tasks. The straight shank ensures stable clamping in chucks and quick bit changes in hand-held and stationary drills.

Advantages

The carbide tip delivers high wear resistance and longer service life compared with standard high-speed steel bits, maintaining cutting performance when working with abrasive materials. The straight shank provides reliable mounting in standard drill chucks and reduces runout for improved hole accuracy. Compact 5 mm diameter enables precise hole placement and is suitable for tight or pre-drilled pilot holes. The bit’s construction supports consistent drilling speed and steady chip evacuation under normal operating conditions.

Suitable for

• Drilling holes in metal sheets and profiles where a 5 mm diameter is required
• Woodworking tasks such as pilot holes, dowel or screw preparation
• Plastic components and composite materials compatible with carbide tips
• General workshop use and on-site drilling with hand-held or bench drills

Key specifications

• Tip material: carbide for improved hardness and wear resistance
• Cutting diameter: 5 mm for precise hole sizes
• Shank type: straight shank for standard chuck compatibility
• Intended use: general-purpose drilling in metal, wood and plastics depending on drill and material
• Suitable tools: compatible with standard hand-held and stationary drills that accept straight-shank bits

How to use

Secure the drill bit in the drill chuck, ensuring the straight shank is fully seated and tightened to minimise runout. Select an appropriate drilling speed and feed rate for the material being drilled; lower speeds are generally recommended for harder metals and higher speeds for softer materials like wood and plastic. Use a cutting fluid or lubricant when drilling metals to extend tip life and improve chip evacuation. Apply steady, even pressure and allow the bit to remove material without excessive force to avoid overheating or premature wear.

Recommendations

Inspect the drill bit before use for signs of wear or damage and replace it when the cutting edge becomes dull. Match drill speed and lubrication to the material: use reduced speed and cutting oil for steel, medium speed for non-ferrous metals, and higher speeds for wood or plastics. Use appropriate personal protective equipment—eye protection and hearing protection—and secure workpieces before drilling.
