Drill bit for concrete Irwin cylindrical 6 mm 10501901

Irwin cylindrical drill bit for concrete, 6 mm diameter, model 10501901 is intended for drilling clean holes in concrete and masonry. The bit’s geometry and carbide tip are designed to withstand the high impact and abrasion typical of concrete drilling. It is supplied with a cylindrical shank suitable for drills and hammer drills that accept a 6 mm straight shank, and is intended for installation of anchors, dowels and fixtures in concrete, brick and similar materials.

Advantages

The Irwin 6 mm concrete bit combines a wear-resistant carbide tip with a flute profile that clears dust efficiently, helping to maintain drilling speed and reduce bit binding. Its cylindrical shank provides secure seating in standard chucks and ensures consistent concentricity during rotation. The bit is optimized for straightforward drilling tasks in masonry where a reliable, single-diameter hole is required.

Suitable for

• Drilling holes for anchors and wall plugs in concrete and brick
• Installing dowels, screws and fixtures into masonry
• Preparing pilot holes for chemical anchors and fasteners
• Use with rotary drills and light hammer drills that accept 6 mm cylindrical shanks

Key specifications

• Diameter: 6 mm
• Intended material: concrete, brick, masonry
• Tip material: carbide cutting tip
• Shank type: cylindrical (straight) shank suitable for 6 mm chucks
• Typical use: rotary and light hammer drilling modes

How to use

Select a drill that accepts a 6 mm cylindrical shank and set the drill to the appropriate mode for masonry—rotary or rotary with hammer depending on drill capability and material hardness. Mark the drilling point and start at low speed to establish the position, then increase speed and apply steady pressure. Periodically withdraw the bit to clear dust from the hole and avoid excessive heat build-up. For deeper holes, peck drilling (short intermittent advances and withdrawals) helps maintain cutting performance and prolong bit life. Use appropriate personal protective equipment, including eye and ear protection and a dust mask.

Usage recommendations

For secure anchor installations, choose a drill depth slightly greater than the anchor length and verify recommended hole diameter for the specific anchor type. When using hammer mode, ensure your drill is compatible with straight-shank masonry bits and avoid excessive side load to prevent tool or bit damage.
