Norseman Drill & Tool Type 761 Machine Screw Bottoming Taps

Norseman Drill & Tool Type 761 Machine Screw Bottoming Taps

Precision Threading for Blind Holes and Repair Applications

Norseman Drill & Tool Type 761 Machine Screw Bottoming Taps are specifically engineered for hand tapping and re-threading operations that require full thread depth at the bottom of a hole. Manufactured from super tough carbon steel, these taps provide the durability, control, and precision needed for maintenance, repair, and general shop work.

Super Tough Carbon Steel Construction

Built for Manual Control and Long Service Life

Type 761 bottoming taps are produced from high-quality carbon steel that delivers excellent toughness and resistance to chipping or breakage during hand tapping. This material allows operators to maintain feel and control while cutting threads, making it easier to correct alignment and avoid damage to existing threads. The rugged construction ensures reliable performance in repeated repair and maintenance applications.

Bottoming Tap Design for Maximum Thread Depth

Ideal for Blind Holes and Finishing Operations

Unlike taper or plug taps, bottoming taps feature a very short chamfer, allowing threads to be cut close to the bottom of blind holes. Norseman Type 761 taps are ideal for finishing threads after starting with a taper or plug tap, or for restoring damaged threads where maximum usable thread length is required. This makes them a critical tool for precision re-threading and tight-clearance applications.

Machine Screw Sizes for Versatile Use

Perfect for Repair and Maintenance Tasks

Type 761 taps are designed for machine screw thread sizes commonly found in automotive, industrial, and mechanical assemblies. They perform well in materials such as mild steel, aluminum, brass, copper, and other non-hardened metals. Their dependable cutting action makes them a trusted choice for maintenance departments, tool rooms, and field service technicians.

Reliable Performance for Hand Tapping

Consistent Results You Can Trust

Designed specifically for manual use, Norseman Type 761 bottoming taps deliver smooth cutting action, clean threads, and excellent control—helping extend tool life while ensuring professional results.
