IMPA: 633051

High Speed Steel Tip Welded Round Nose Boring Tool Bits (IMPA 633051)

This high speed steel (HSS) tip welded boring tool bit is a precision cutting tool engineered for internal boring operations in demanding marine engineering and ship repair environments. The round nose cutting edge is formed from a durable HSS tip, welded onto a robust steel shank for maximum strength and longevity.

Ideal for use on lathes and boring machines, this tool bit effectively enlarges holes, refines internal diameters, and creates accurate contours. The round nose profile reduces cutting stress, resists chipping, and promotes a smooth, polished surface finish. Suitable for machining steel, stainless steel, cast iron, and non-ferrous metals, this IMPA 633051 tool bit is an essential addition to any ship chandler's cutting tools inventory.

Frequently Asked Questions

What is a welded HSS tip boring tool bit?

It is a cutting tool where a high speed steel cutting edge is welded to a lower-cost steel shank, combining the high heat and wear resistance of HSS with the durability and economy of a steel body.

Can this tool bit be used for both roughing and finishing cuts?

Yes, the round nose geometry allows for stable cutting in both moderate roughing and finish boring operations on various machine tools.

How should I store these boring tool bits?

Store them in a dry, corrosion-free environment. Keep the cutting edges protected from impact and avoid exposure to moisture to preserve sharpness.

Does this tool bit require any special holder?

It is designed to be clamped into standard boring bar holders or tool posts compatible with the shank size. Always match the holder to the shank cross-section.
