Westward HSS Tool Bit 5/8 Inch

This Westward high-speed steel tool bit measures 5/8 inch in width and height with a 4 inch overall length. It features a 15 degree bevel angle and is ground for both right-hand and left-hand cutting operations. The blank arrives ready for shaping to specific lathe profiles.

Suited for manual lathe work

Machinists who need a durable HSS blank for turning, facing or threading will find this size practical. It is not intended for indexable insert holders or CNC tool changers that require precision-shanked tooling. Buyers who want pre-ground geometry or coated cutting edges should look elsewhere.

Handles general-purpose steel

The 5/8 inch square cross-section provides enough mass for moderate cuts in mild steel, aluminium and brass without excessive deflection. Heavy roughing passes on tough alloys or deep boring operations will exceed the rigidity of this blank diameter. High-volume production runs demanding long edge life between regrinds will also reach its limits quickly.

Questions about this item

What size tool holder do I need for the 5/8 inch square shank on this bit?

The bit has a 5/8 inch square shank, so it fits a standard 5/8 inch tool post or holder.

Can I use this high-speed steel blank on my older manual lathe?

Yes, the HSS material works well on manual lathes for general turning, facing, and light cuts.

How do I check the 15 degree bevel is ground correctly after mounting?

Use a protractor or angle gauge against the beveled edge; it should read 15 degrees from the top face.
