Drill Bit STANLEY STA51033 universal cylindrical 35 mm

STANLEY STA51033 universal cylindrical 35 mm drill bit is designed for straightforward drilling tasks that require a clean 35 mm bore. Compatible with standard drill chucks, this bit is intended for use in portable drills and drill presses and addresses common installation and repair needs in construction and renovation work. The cutting diameter of 35 mm and universal cylindrical shank make it a practical choice when a moderately large, precise hole is required in typical building materials.

Advantages

The universal cylindrical design ensures stable seating in standard chucks and reduces wobble during drilling. A 35 mm cutting diameter provides a consistent hole size suitable for pipe entries, larger fasteners, and fixture mounts. The bit is engineered for general-purpose use across a range of common materials, offering predictable drilling performance and ease of replacement when used in both handheld drills and drill presses.

Suitable for

• Drilling 35 mm holes for pipes and conduits in walls and panels
• Creating openings for larger fasteners and mounting hardware
• General installation and repair tasks in construction and renovation

Key specifications

• Cutting diameter: 35 mm
• Shank type: cylindrical (suitable for standard chucks)
• Intended use: general-purpose drilling
• Compatible tools: portable drills and drill presses
• Typical materials: common construction materials (wood, soft plastics, plasterboard)

How to use

Secure the drill bit in a properly sized chuck and tighten according to the drill manufacturer's instructions. Mark the drilling position and, if necessary, clamp the workpiece to prevent movement. Start drilling at low speed to establish the pilot contact, then increase speed steadily while applying consistent axial pressure. Withdraw the bit periodically to clear debris and reduce heat build-up. For repetitive or precision holes, use a drill press or guide to maintain perpendicular alignment.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and feed pressure to the material: lower speeds for harder or reinforced areas, higher speeds for soft materials. Inspect the bit before use for damage and replace if worn or chipped to maintain hole quality and safe operation.
