Single Point Cutting Tools Model 47 & Model 48

Our Single Point Tools Model 47 & Model 48 are precision-engineered cutting tools designed for a variety of lathe operations common in marine workshops and shipboard maintenance. These tools are manufactured from high-grade high-speed steel (HSS), ensuring excellent hardness, wear resistance, and the ability to maintain a sharp cutting edge even under demanding conditions. Available in two orientations, these tools provide flexibility to perform turning, facing, and shaping tasks on ferrous and non-ferrous metals.

Model 47 features a right-hand configuration, ideal for conventional cutting operations, while Model 48 is the left-hand counterpart for reverse-direction machining. Made to fit standard lathe tool posts, these single point tools deliver reliable performance, whether you are repairing a propeller shaft, manufacturing a custom bushing, or maintaining deck machinery. Their ground surfaces and clean geometry reduce friction and improve chip flow for a smooth finish.

Built to withstand the corrosive saltwater environment, these tools are the practical choice for marine engineers. Keep a set onboard to ensure you are always prepared for routine maintenance and emergency repairs.

Frequently Asked Questions

What is the difference between Model 47 and Model 48 single point tools?

Model 47 is a right-hand tool designed for cutting operations moving from right to left, while Model 48 is the left-hand version for opposite direction cutting. This allows you to machine a wide range of components without needing to change the tool orientation.

What types of metal can these tools cut?

These high-speed steel tools are effective for machining mild steel, stainless steel, aluminum, brass, and bronze. They are suitable for both roughing and finishing of marine-grade alloys, as long as proper cutting speeds and feeds are used.

Will they fit my lathe tool holder?

Both models come in standard square shank sizes: Model 47 features a 10 mm x 10 mm shank and Model 48 features a 12 mm x 12 mm shank, which fit the majority of common quick-change tool posts and tool holders found in shipboard workshops.

How should I store these tools to prevent corrosion?

After use, clean the tools and apply a light coat of machine oil to the cutting edges. Store them in a dry tool cabinet. Avoid exposing them to salt spray for extended periods, and re-sharpen when the edge shows signs of wear.
