DEWALT Extreme 2 Metal Drill Bits - UTTK6967

The Split Pilot Point eliminates the need for a center punch and prevents the drill bit from 'walking' or slipping on the material surface upon initial contact, ensuring a precise start.

The DEWALT Extreme 2 Metal Drill Bit is suitable for drilling steel alloys up to 900 N/mm² tensile strength. For specific stainless steel grades, check their tensile strength. For harder stainless steels, a bit designed for tougher materials might be more appropriate.

This bit is suitable for drilling steel (alloyed and non-alloyed up to 900 N/mm²), as well as wood and plastic materials.

The Extreme 2 Metal Drill Bit is designed to minimize burrs. Ensure the bit is sharp, use an appropriate speed, and apply steady pressure. Supporting the backside of the material can also help.

While not always mandatory, using a cutting fluid or lubricant is highly recommended, especially for extended drilling sessions or harder metals. It helps reduce heat, prolongs the bit's life, and improves the quality of the hole.

Recommended speeds vary by material and drill. Generally, lower speeds are best for metal (e.g., 300-600 RPM for steel), while higher speeds can be used for wood and plastic. Always consult your drill's manual and consider the bit size.

This bit is rated for steel up to 900 N/mm² tensile strength. It may not be the optimal choice for very hard or hardened steels, which typically require specialized drill bits.

Ensure the bit is properly seated and tightened in the drill chuck. Verify that the split pilot point is making contact and engaging the material as designed. For very hard materials, ensure you are not exceeding the material's tensile strength limit.

Reduce drilling speed slightly and apply consistent, steady pressure. Ensure the bit is sharp. For thin metal, consider using a backing material or a drill press for stability. Clean the bit after use to prevent residue buildup.

Reduce drilling speed and apply less pressure. Use a cutting fluid or lubricant specifically designed for metal drilling. Allow the bit to cool periodically between holes.

Excessive force or bending can cause breakage. Ensure you are drilling straight and not forcing the bit. Check that the material's hardness is within the bit's specified range (up to 900 N/mm²).
