Drill bits set STANLEY STA56035 — masonry SDS-plus? 5 pcs: 4, 5, 6, 8, 10 mm

STANLEY STA56035 is a 5-piece masonry drill bit set for use with SDS-plus compatible rotary hammers and hammer drills. The set contains five solid carbide-tipped bits in diameters 4, 5, 6, 8 and 10 mm that are intended for drilling precise holes in concrete, brick, block and other masonry materials. These bits are designed for common construction and renovation tasks such as creating anchor and plug holes or through-holes for installations.

Advantages

The masonry bits feature carbide tips and a flute geometry suited to efficient debris removal during percussive drilling, reducing clogging and heat buildup. The SDS-plus shank ensures secure, quick bit changes and consistent transfer of impact energy from the tool to the bit. The range of diameters covers small to medium hole requirements commonly encountered in fixing, electrical and plumbing preparatory work.

Suitable for

• Drilling anchor and plug holes in concrete, brick and aerated block
• Making through-holes for wiring and small conduits
• Renovation tasks that require multiple hole sizes without frequent tool changes
• Use with SDS-plus rotary hammers and compatible hammer drills

When it may not be suitable

This set is intended specifically for masonry and concrete work; it is not optimized for drilling in metal, wood, tile glazed ceramics, or glass. For very large diameter holes, core drilling or applications requiring diamond tooling, this set will be insufficient. High-precision or finish drilling where carbide masonry bits might cause chipping on thin ceramic tiles should be avoided.

Key specifications

• Bit type: masonry drill bits with carbide tips
• Shank type: SDS-plus
• Number of pieces: 5
• Included diameters: 4 mm, 5 mm, 6 mm, 8 mm, 10 mm
• Typical use: percussion drilling into concrete, brick and block

How to use

Select the required diameter based on the anchor or plug size. Fit the SDS-plus bit into the rotary hammer or hammer drill until it locks. Use the hammer drilling mode and apply steady pressure while allowing the tool and bit to do the work; avoid excessive lateral force. Periodically withdraw the bit to clear dust from the hole and prevent overheating. For deeper holes, drill in stages and check fit with the fastener. When finished, retract the bit and clean the flutes before storage.

What to consider before purchase

• Confirm your rotary hammer or hammer drill accepts SDS-plus shanks
• Match the bit diameters to the anchors, plugs or conduits you plan to use
• Consider whether you need larger diameters or speciality bits (tile, metal, core) in addition
• Evaluate expected usage frequency to determine if professional-grade or heavy-duty bits are required

Usage recommendations

For best results, use the bits in hammer drilling mode at appropriate speed settings for masonry, keep the bits cool by clearing dust frequently, and replace bits showing excessive wear or chipped tips to maintain hole quality and drilling efficiency.
