Frequently Asked Questions
What materials can I machine with these single point tools?
These tools are ideal for cutting carbon steel, alloy steel, stainless steel, brass, bronze, and aluminum. For best results, ensure appropriate cutting speed and feed rates.
What is the difference between Model 39 and Model 40?
The two models differ in shank size. Model 39 has a 1/4-inch shank, while Model 40 has a 3/8-inch shank. Choose based on your lathe tool holder size and required depth of cut.
Can these tools be reground?
Yes, high-speed steel tools are typically regrindable. Reshape the cutting edge on a bench grinder to suit your specific machining needs.
Are the tools corrosion resistant for marine use?
Plain HSS is not corrosion-proof, but these tools are oiled to resist rust and are suitable for marine workshops. Always wipe and apply light oil after use to prevent corrosion.
