Irwin 10501944 Twist Drill Bit 4 mm

The Irwin 10501944 Speedhammer Plus twist drill bit is a high-performance tool specifically engineered for drilling into hard materials. With a 4 mm diameter and an SDS-plus shank, this drill bit is designed to provide stability and precision during intensive drilling operations. Its construction focuses on durability and efficient material removal, making it a reliable choice for both professional contractors and home improvement enthusiasts who require consistent results in masonry and concrete work.

Advantages

This drill bit features a unique single flute design that significantly improves the speed of dust extraction, which in turn reduces vibrations and prevents the tool from clogging during operation. The patented extra short drill bit head is engineered to handle the majority of the workload, which enhances the overall durability of the bit and allows for faster penetration into tough surfaces. By clearing drilling dust directly into the flute, the design minimizes friction and heat buildup, ensuring a longer service life and more efficient performance compared to standard drill bits.

Suitable for

• Drilling into concrete
• Masonry applications
• Brick and block work
• Granite drilling

This drill bit is not suitable for drilling into wood, metal, or plastic, as its geometry and SDS-plus shank are specifically optimized for masonry and concrete materials. Using this bit on inappropriate materials may result in poor hole quality or damage to the drill bit and the workpiece.

Key specifications

• Type: Twist drill bit
• Diameter: 4 mm
• Length: 160 mm
• Shank type: SDS-plus
• Cutting edges: 2

To use the Irwin Speedhammer Plus drill bit, ensure your rotary hammer drill is set to the hammer-drilling mode. Insert the SDS-plus shank into the chuck until it clicks into place, ensuring a secure fit. Apply steady, moderate pressure while drilling to allow the bit to clear dust effectively. Avoid excessive force, as the design of the bit is intended to do the work efficiently without needing extreme pressure from the user.

What to consider before purchase

• Verify that your power tool is compatible with an SDS-plus shank system.
• Ensure the 4 mm diameter meets your specific project requirements.
• Confirm the material you are drilling is compatible with masonry-grade bits.

For optimal performance and longevity, allow the drill bit to cool down periodically during heavy-duty use and ensure the SDS-plus chuck is kept clean and lightly lubricated.
