Frequently Asked Questions
What is a High-Speed Steel Tip Welded Tool Bit?
A high-speed steel (HSS) tip welded tool bit consists of a HSS cutting tip brazed or welded to a steel shank. It is used primarily for lathe operations like turning and facing in metalworking workshops.
Can this tool bit machine stainless steel?
Yes, HSS tool bits can machine stainless steel when run at appropriate cutting speeds with coolant. They are particularly useful in ship maintenance where stainless steel parts are common.
What are the dimensions of Model No. 64?
Model No. 64 refers to a square nose straight tool bit with a nominal shank size of 1/2 inch × 1/2 inch and an overall length of 6 inches (12.7 mm × 12.7 mm × 152 mm).
What does IMPA 633113 cover?
IMPA 633113 is the International Marine Purchasing Association code for cutting tools, specifically high-speed steel tool bits and related lathe cutting tools. This makes it easy to identify in ship chandler catalogs.
