Drill bit STANLEY STA54057 8 mm x 210 mm for rotary hammer, 1 pc

STANLEY STA54057 8 mm x 210 mm drill bit is made for use with rotary hammers and SDS-plus chucks. With an 8 mm working diameter and a 210 mm overall length, this single-piece bit is intended for medium-duty drilling in concrete and masonry. It is suitable for creating holes for anchors, conduit and cable routes during construction and renovation tasks, offering the compatibility and dimensions needed for common installation work.

Advantages

The SDS-plus shank ensures quick, secure seating in compatible rotary hammers and reduces bit slippage. The geometry and material of the cutting tip are designed for efficient penetration of concrete and masonry while maintaining hole accuracy. The 210 mm length gives added reach for drilling through thicker materials or working into recessed areas without sacrificing bit stability.

Suitable for

• Drilling anchor holes in concrete and masonry
• Creating passages for pipes and electrical conduits
• Medium-duty renovation and installation tasks
• Situations requiring an 8 mm diameter hole with extended reach

How to use

Fit the STANLEY STA54057 bit into an SDS-plus rotary hammer according to the tool manufacturer’s instructions. Mark the drilling position on the work surface and use appropriate personal protective equipment. Start drilling at low speed to establish the hole, then apply steady pressure and operate the hammering function for efficient penetration of concrete or masonry. Withdraw the bit periodically to remove debris and prevent binding. After drilling, clear the hole of dust before inserting anchors or conduits.

Usage recommendations

Use with a rotary hammer that supports SDS-plus bits and select the hammer mode suitable for reinforced or plain concrete. For prolonged service life, avoid excessive lateral force and remove accumulated dust from the hole between drilling intervals. Match drill diameter and depth to the anchor or conduit specifications for a secure installation.
