CMT 310.080.42 HW Dowel Drill Bit D=8mm I=27mm L=57.5mm S=10x20mm

The CMT 310.080.42 HW dowel drill bit is a precision-engineered tool designed for high-performance boring in wood and wood-based materials. With a diameter of 8mm and a cutting length of 27mm, this bit is specifically optimized for professional woodworking machinery, ensuring consistent results in demanding production environments. The carbide construction provides exceptional durability and heat resistance, allowing for clean, accurate holes that are essential for high-quality furniture assembly and cabinet manufacturing.

Advantages

This dowel drill bit stands out due to its high-grade carbide composition, which maintains a sharp cutting edge significantly longer than standard steel bits. The geometry of the bit is designed to minimize tear-out, resulting in smooth hole walls that facilitate easier dowel insertion and stronger joints. Its robust build quality ensures stability during high-speed operation, reducing vibration and increasing the overall lifespan of the tool in industrial settings.

Suitable for

• Furniture manufacturing
• Cabinet assembly
• Drilling precise holes for dowel joints
• Working with solid wood, particle board, and MDF

When it may not be suitable

This drill bit is not intended for use with metal, stone, or masonry materials, as these will cause immediate damage to the carbide cutting edges. It is also not suitable for handheld power drills, as it is specifically designed for use with stationary boring machines and CNC equipment.

Key specifications

• Diameter: 8mm
• Cutting length: 27mm
• Overall length: 57.5mm
• Shank dimensions: 10mm x 20mm
• Material: HW (Carbide)

How to use

To achieve optimal results, ensure the drill bit is securely mounted in the collet or chuck of your boring machine according to the manufacturer's instructions. Verify that the machine speed is set appropriately for the material being processed. Always ensure the workpiece is firmly clamped to prevent movement during the drilling process. Regularly inspect the bit for signs of wear or resin buildup and clean it with an appropriate solvent to maintain cutting efficiency.

What to consider before purchase

• Verify that your machine's collet size matches the 10mm x 20mm shank specifications.
• Ensure the required hole diameter and depth match the 8mm and 27mm dimensions of this bit.
• Confirm compatibility with your specific boring machine or CNC setup.

Usage recommendations

For best performance and longevity, maintain a consistent feed rate and ensure the drill bit is kept clean from wood dust and resin. Replace the bit immediately if you notice dulling or chipping to prevent damage to your workpieces.
