Drill bit STANLEY STA58004 — 8 mm diameter, 120 mm length, single piece

Single STANLEY STA58004 — 8 mm diameter, 120 mm length drill bit designed for drilling in masonry. This single-piece drill bit offers a medium-size cutting diameter and a 120 mm overall length to give additional reach for common construction, repair and DIY tasks. The bit is intended for use with compatible rotary drills and hammer drills when working with brick, concrete and similar materials.

Advantages

The 8 mm diameter provides a balance between drilling speed and hole stability, while the 120 mm length delivers extended reach for deeper holes or through-material drilling. Being a single piece, the bit is simple to store and replace, and its geometry is tailored for effective masonry penetration. The product is branded by STANLEY, which ensures consistent manufacturing tolerances and compatibility with standard drill chucks.

• General repair and renovation tasks requiring medium-size holes
• DIY projects involving block, stone or similar dense materials

Key specifications

• Diameter: 8 mm
• Overall length: 120 mm
• Intended material: masonry (brick, concrete, stone)
• Quantity: 1 piece
• Compatibility: fits standard drill chucks designed for 8 mm bits

How to use

Secure the drill bit in the drill chuck ensuring it is properly tightened and centered. Select the appropriate drill mode (rotary or hammer) based on the masonry hardness and the drill manufacturer's recommendations. Mark the drilling position, start at low speed to create a pilot groove, then increase speed and apply steady pressure. Withdraw the bit periodically to clear debris and prevent overheating. After reaching the required depth, remove the bit and clean the hole before inserting anchors or fasteners.

Usage recommendations

Use protective eyewear and hearing protection when drilling masonry. For consistent results, match the drill mode and speed to the material: hammer mode for concrete or hard stone, rotary for softer masonry. Avoid excessive side pressure to prolong bit life and use compressed-air or a brush to remove dust between passes.
