Drill bit Irwin 10501979 twist drill bit 10 mm for rotary hammer 1 pc

Irwin 10501979 twist drill bit with a 10 mm diameter is designed for use with rotary hammers and supplied as a single piece. The bit features a patented extra short carbide tip and a single-flute geometry that together provide efficient chip evacuation and faster penetration when drilling into compatible masonry and concrete materials. The brazed carbide tip is attached using a high-temperature process to increase heat resistance and extend service life. The shank is compatible with SDS rotary hammers, allowing straightforward installation and reliable holding during impact drilling.

Advantages

The patented extra short carbide tip takes most of the workload, improving durability and drilling speed while its self-centering geometry simplifies control. A concave cutting profile and aggressive head design deliver faster penetration and maintain cutting performance. The single-flute design increases waste removal capacity, reducing clogging and improving drilling efficiency. High-temperature brazing creates a strong bond between tip and shank for enhanced tip life under heavy use.

Suitable for

• Drilling 10 mm holes in masonry, concrete and brick with an SDS rotary hammer
• Professional construction tasks requiring repeatable, reliable holes
• DIY projects where precise, fast drilling into hard substrates is needed

Key specifications

• Diameter: 10 mm
• Tip material: carbide (brazed)
• Tip design: patented extra short carbide tip with concave cutting angles
• Flute design: single flute for increased waste removal capacity
• Drilling speed: up to 20% faster vs conventional designs (manufacturer data)
• Compatibility: SDS rotary hammer shank fit
• Brazing temperature: tip brazed at high temperature for improved heat resistance

How to use

Install the drill bit into the rotary hammer's SDS chuck until it locks in place. Select the hammer or rotary mode appropriate for the substrate and set the correct rotation speed if the tool offers variable control. Position the bit on the marked drilling point using the self-centering tip to maintain alignment, then apply steady pressure while allowing the tool and the patented tip geometry to do the cutting. Withdraw the bit periodically to clear debris if drilling deep holes, and avoid excessive side loads that could reduce bit life.

Usage recommendations

For best results use the Irwin 10 mm twist drill bit with a compatible SDS rotary hammer in hammer-drill mode on masonry and concrete. Ensure the drill speed and feed pressure are appropriate for the substrate, clear debris regularly due to the single flute design, and replace the bit when wear reduces drilling performance. Store in a dry place to protect the brazed carbide tip from unnecessary damage.
