Bosch EXPERT HEX-9 TCT Drill Bit - 8 x 250mm

This bit is designed for a wide range of materials including concrete, brick, soft tile, wood, granite, and metal. It can also be used on plastic.

Yes, it's compatible with most standard drill drivers and impact drivers that can securely hold a hex shank.

Use impact mode for harder materials like concrete and stone. Use rotary mode for softer materials such as wood, plastic, and metal.

It provides a precise starting point for drilling, preventing the bit from skidding or wandering on the surface of hard materials.

The hex shank ensures a strong, non-slip connection with your drill's chuck, allowing for maximum torque transmission and better control.

The EXPERT HEX-9 is a multi-construction bit offering significantly improved precision (up to 5x more than a Bosch CYL-3) and versatility across different material types.

This specific model is 8mm in diameter and 250mm in length.

Ensure the hex shank is fully and securely seated in the drill chuck. Check that the drill chuck itself is not damaged and is tightening properly.

Verify you are using the correct drilling mode (rotary vs. impact) for the material. Ensure your drill's speed and power settings are appropriate. Consider using a drilling lubricant for metal applications. Check for material buildup on the bit flutes.

This can occur if the bit is dropped or used on extremely hard, brittle materials beyond its intended scope, or if used improperly in impact mode on delicate materials. Inspect for damage and consider replacement if severe.

Ensure the drill is set to impact mode. Apply steady, even pressure. If drilling into heavily reinforced concrete, specialized concrete bits might be more effective for prolonged use.
