Drill bit for concrete STANLEY STA53085 — cylindrical 5 mm

STANLEY cylindrical concrete drill bit, 5 mm diameter, designed for drilling clean holes in concrete and masonry. The shaft is cylindrical to fit rotary hammers or hammer drills with a straight shank chuck. This 5 mm bit is intended to create a single, precise hole size for applications such as anchor and plug installation or routing small conduit through concrete surfaces. The bit is suitable for both professional tradespeople and DIY users who need consistent results when drilling into hard substrates.

Advantages

The STANLEY 5 mm cylindrical concrete drill bit delivers accurate hole diameter and stable drilling performance in concrete and masonry. Its cylindrical shank ensures compatibility with a wide range of hammer drills and rotary hammers that accept straight shanks. The bit is made to withstand impact drilling forces and maintain cutting geometry for repeated use when installing anchors, dowels, or plugs. Its single-diameter design simplifies selection when a specific 5 mm hole is required.

Suitable for

• Drilling 5 mm holes in concrete for plastic plugs and anchors
• Preparing masonry for lightweight fixings and fasteners
• Creating openings for small electrical conduit or cable runs
• General repair and renovation tasks requiring precise 5 mm holes

Key specifications

• Diameter: 5 mm
• Shank type: cylindrical (straight) shank
• Intended material: concrete and masonry
• Drill type compatibility: rotary hammer or hammer drill with straight shank chuck
• Use case: single-diameter drilling for anchors, plugs, and conduit

How to use

Select appropriate personal protective equipment such as safety glasses and hearing protection before drilling. Secure the workpiece or mark the drilling location on the concrete surface. Fit the cylindrical shank into a compatible hammer drill or rotary hammer chuck and set the drill to hammer mode if required for concrete. Position the bit at the marked point, apply steady pressure, and start drilling at moderate speed until the desired hole depth is reached. Withdraw the bit periodically to clear dust and debris for a cleaner hole and reduced wear.

Usage recommendations

For best performance, use the bit with a hammer drill or rotary hammer that supports cylindrical shanks and select an appropriate drilling speed and hammer setting for the concrete hardness. Clear drilling dust frequently and replace the bit when cutting edges show excessive wear to maintain hole quality and reduce breakage risk.
