Drill bit Michelin 10.0 x 430 mm — solid-shank masonry drill

Michelin drill bit 10.0 x 430 mm — solid-shank masonry drill designed for drilling through masonry and concrete. The 430 mm overall length provides extended reach for deep holes while the 10.0 mm diameter corresponds to common anchor and dowel sizes. Solid-shank construction ensures stable performance in both rotary and percussion drilling modes, offering precise boreholes for installation and repair tasks.

Advantages

The solid-shank design reduces wobble and improves centring when used with rotary and hammer drills, delivering consistent hole dimensions. A long 430 mm length allows access to recessed or deep fixing points without the need for extensions. Compatibility with standard 10.0 mm anchors and dowels simplifies fastener selection for construction and mounting work. The hardened and ground flute profile helps with chip evacuation and maintains drilling efficiency during repeated use.

Suitable for

• Drilling anchor and dowel holes in masonry, brick and concrete
• Installation of fixtures, railings and electrical boxes
• Repair and renovation works requiring deep or recessed holes
• Use with rotary and percussion (hammer) drills for construction tasks

Key specifications

• Diameter: 10.0 mm
• Overall length: 430 mm
• Type: solid-shank masonry drill bit
• Suitable drilling modes: rotary and percussion (hammer)
• Recommended materials: masonry, brick, concrete

How to use

Secure the drill bit firmly in the drill chuck and set the drill to the appropriate mode (rotary for softer masonry, percussion for concrete). Mark the drilling position and start at low speed to create a pilot indentation, then increase speed and apply steady pressure. Periodically withdraw the bit to clear debris and prevent overheating. For deep holes use step drilling technique or withdraw regularly to remove dust and chips; ensure proper anchor depth before inserting fasteners.

Usage recommendations

Use appropriate personal protective equipment including eye protection and a dust mask. When drilling in reinforced concrete avoid prolonged contact with rebar; if rebar is encountered, change the drilling position or use a specialized bit. Store the drill bit in a dry place and inspect for wear; replace when the tip is worn or when drilling performance degrades.
