Concrete SDS+ drill bit MODECO 8 mm MN-61-137

Concrete SDS+ drill bit MODECO 8 mm MN-61-137 is a rotary hammer accessory made for drilling into concrete, masonry and natural stone with SDS+ compatible hammer drills. The 8 mm diameter bit is intended for standard installation jobs such as fixing anchors, dowels and installing electrical boxes or plumbing sleeves. Its tip and flute geometry are designed to provide efficient chip removal and stable drilling performance during repetitive use.

Advantages

The MODECO 8 mm SDS+ drill bit offers a robust carbide tip and optimized flute profile that enhance penetration into hard substrates and reduce clogging. Its SDS+ shank ensures secure, wobble-free mounting in compatible rotary hammers and quick bit changes. The bit's construction aims for consistent hole dimensions and prolonged service life under normal working conditions.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Creating openings in masonry and brickwork for installations
• Preparing holes for electrical and plumbing fixture mounting
• General maintenance and construction tasks requiring 8 mm holes

Key specifications

• Diameter: 8 mm
• Shank type: SDS+ compatible
• Intended material: concrete, masonry, natural stone
• Tip: carbide-tipped for improved wear resistance
• Flute design: spiral flute for efficient dust and chip removal

How to use

Install the SDS+ drill bit into the chuck of an SDS+ rotary hammer until it engages securely. Select the hammer-drill mode appropriate for concrete drilling and apply steady axial pressure without excessive force. Start drilling at low speed to establish the hole, then increase power as needed. Periodically withdraw the bit to clear accumulated dust and chips, improving cooling and drilling efficiency. Use personal protective equipment such as safety glasses, hearing protection and a dust mask when working.

Usage recommendations

For best results, match drill speed and impact settings to the substrate hardness; allow the bit to cool between prolonged drilling sessions and replace the bit when tip wear affects hole quality. Use appropriate anchors and dowels sized for 8 mm holes and follow manufacturer instructions for fastener installation.
