Drill Bit MODECO SDS+ 14 mm MN-61-929 – rotary SDS-plus masonry bit 14mm

MODECO SDS+ 14 mm drill bit MN-61-929 is a rotary masonry bit with a 14 mm working diameter designed for use with SDS-plus hammer drills. Intended for drilling into masonry, concrete and natural stone, this bit combines an SDS-plus shank for fast, reliable coupling and a geometry optimised for percussion drilling. It is suitable for medium-duty drilling and light chiselling tasks on construction sites, during renovation works or for installation of fixings and anchors.

Advantages

The SDS-plus connection provides secure retention in compatible hammer drills and efficient transfer of impact energy, which improves drilling speed and reduces wear on the tool and bit. The 14 mm diameter offers a balance between hole size and drilling speed for common anchor and dowel applications. The bit’s cutting head and flute design evacuate dust and debris effectively during percussion drilling, supporting stable progress and longer service life when used in appropriate materials.

Suitable for

• Drilling holes for anchors, dowels and fixing plugs in masonry
• Making holes in concrete and reinforced concrete for medium-depth fixings
• Creating openings in natural stone and brickwork for installations
• On-site renovation and construction tasks requiring SDS-plus hammer drilling

Key specifications

• Working diameter: 14 mm
• Shank type: SDS-plus
• Intended material: masonry, concrete, natural stone
• Drilling method: rotary with percussion (hammer drilling)
• Typical use: medium-duty drilling and light chiselling

How to use

Insert the SDS-plus shank into the hammer drill’s chuck until it locks. Select the hammer drilling mode on the tool before starting. Position the bit tip at the marked drilling point, apply steady forward pressure and operate the drill at appropriate speed for the material. Withdraw the bit periodically to clear dust from the hole and allow cooling when drilling deep or extended holes. Use appropriate personal protective equipment such as eye and ear protection and a dust mask.

Usage recommendations

For best results, match the drill speed and percussion setting to the material: lower speeds and stronger percussion for hard concrete, moderate speeds for masonry and brick. Avoid using the bit in rotary-only mode on very hard materials. Replace the bit if the cutting head shows excessive wear or if drilling performance decreases significantly.
