Drilling bit, Bosch 2608628351 — shank 8 mm, working Ø 23.7 mm, working length 12 mm

Bosch 2608628351 drilling bit with an 8 mm shank, 23.7 mm working diameter and 12 mm working length is a precision drill accessory designed for creating round holes where the specified diameter and short working length are required. It fits tools that accept an 8 mm shank and is intended for use in applications that require a stout shank and a relatively shallow drilling depth.

Advantages

The drill bit provides a defined 23.7 mm hole diameter with a short 12 mm effective cutting length for controlled penetration and reduced risk of over-drilling. The 8 mm shank ensures stable clamping in chucks designed for metric shanks, improving concentricity and reducing runout. Manufactured to Bosch quality standards, it is suitable for precise, repeatable drilling tasks where consistent diameter and a robust connection to the tool are important.

Suitable for

• Drilling shallow, precise holes in compatible construction materials
• Use with handheld drills and drill presses accepting an 8 mm shank
• Applications requiring a specific 23.7 mm hole diameter and limited depth
• Tasks where stable clamping and concentricity are important

Key specifications

• Shank diameter: 8 mm
• Working diameter: 23.7 mm
• Working (cutting) length: 12 mm
• Compatibility: designed for chucks and holders that accept 8 mm shanks

How to use

Secure the drill bit in the drill chuck, ensuring the 8 mm shank is fully seated and tightened to minimize slippage. Select an appropriate rotational speed and feed rate for the material being drilled, and position the workpiece firmly with clamps or a vice. Begin drilling with light, steady pressure to establish the hole and then proceed at a consistent rate until the required 12 mm depth is reached. Retract periodically if drilling materials that produce chips or dust to clear the cutting area and avoid overheating.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and gloves. Match drill speed and feed to the work material and consider pilot drilling if required for precision alignment. Inspect the bit for wear or damage before use and replace if cutting performance degrades.
