Hole Saw STANLEY STA81112 for masonry and concrete, TCT, diameter 33 mm

TCT hole saw STANLEY STA81112 with a 33 mm cutting diameter is designed for creating circular openings in masonry and concrete. The tool has tungsten carbide-tipped teeth that provide improved wear resistance and consistent cutting performance when drilling into hard materials. It is intended for use with compatible drill arbors and standard drills to make holes for anchors, pipes, electrical conduits and other fixtures during construction and renovation work.

Advantages

The tungsten carbide-tipped (TCT) cutting edges deliver longer life and maintain sharpness when cutting abrasive materials such as concrete, brick and mortar. The 33 mm diameter produces accurate, clean holes suitable for standard anchors and small-diameter pipes. Designed for use with standard drill arbors, the hole saw offers straightforward fitting and reliable engagement with most drills. Its construction focuses on stable cutting and reduced tool wear under typical masonry drilling conditions.

Suitable for

• Drilling holes for wall anchors in concrete and brick
• Creating openings for small-diameter pipes and conduits
• Installing electrical boxes, cable passages and fixtures in masonry
• General renovation and construction tasks requiring circular holes in hard substrates

Key specifications

• Cutting diameter: 33 mm
• Cutting material: tungsten carbide-tipped (TCT) teeth
• Intended material: masonry, concrete, brick, mortar
• Compatibility: for use with compatible drill arbors and standard drills
• Application: dry drilling for anchors, pipes and cable passages

How to use

Secure a compatible drill arbor to the hole saw and tighten according to the arbor manufacturer's instructions. Mark the drilling location and, if possible, start with a pilot mark or small center punch to prevent wandering. Position the hole saw square to the surface, apply steady pressure and run the drill at moderate speed; avoid excessive force to reduce chipping and overheating. Withdraw the hole saw occasionally to clear dust and debris and, when the cut is complete, remove residual material from the hole saw teeth before storage.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, dust mask and hearing protection. When drilling deep or dense concrete, consider intermittent drilling and allow the tool to cool to extend cutting life. Ensure the drill and arbor are rated for masonry use and compatible with the hole saw size to maintain safe operation.
