Bosch EXPERT Self Cut Speed Spade Bit - 13 x 152mm

This bit is specifically designed for drilling into various types of wood. It is not recommended for use on metal, masonry, plastic, or other hard materials.

The threaded tip engages with the wood fibers and pulls the bit forward into the material with minimal downward pressure from the user, making drilling easier and faster.

Yes, the 1/4" hex shank is impact-rated, making it suitable for use with impact drivers for added power and speed.

The EXPERT Self Cut Speed bit features a unique wave-shaped spade design that efficiently ejects wood chips, preventing clogging and allowing for continuous, high-speed drilling. The self-feeding tip also contributes to faster progress by reducing the need for manual plunging.

The key differences are the self-feeding threaded tip for easier penetration and the wave-shaped flute for superior chip removal, leading to significantly faster drilling speeds and less user effort compared to standard spade bits.

After each use, clear any wood debris from the flutes. You can use a brush or compressed air. Store in a dry location to prevent rust.

The shank is a 1/4" hex shank, designed for secure grip in drill chucks and compatibility with impact drivers.

Ensure the drill is rotating in the correct direction (forward). Apply steady, light pressure; the self-feeding tip should engage automatically. Check that the wood is not excessively hard or contains obstructions.

Clean wood chips from the wave-shaped flute. Ensure the bit is sharp and undamaged. If using an impact driver, ensure it is set to an appropriate speed for the material. Excessive heat may indicate friction from chip buildup or a dull bit.

Ensure you start the drill at a low speed to allow the self-feeding tip to properly engage the wood surface. Maintain a perpendicular angle to the material.

Cease use immediately if the tip is bent or broken. This indicates the bit was likely used on a material it was not designed for or subjected to excessive force. Inspect for further damage to the bit and consider replacement.
