Value Collection 47198 Single Point Carbide Boring Tool Bit

Product Description

The VALUE COLLECTION 47198 is a single-point tool bit designed for square shank boring operations on a lathe. It features a K21 solid carbide tip brazed to a square shank body, providing the hardness and wear resistance needed for boring metal workpieces. The shank measures 0.5 inches wide by 0.5 inches tall, with an overall length of 2.5 inches. The neutral cutting direction makes it suitable for straight-in boring passes. A nose radius of 0.03125 inches (1/32 inch) is ground into the tip, controlling surface finish and chip load. Machinists and tool and die professionals typically install this bit in a boring bar holder on a manual or CNC lathe.

This tool bit fits standard lathe boring bar setups used in job shops, maintenance machining, and production turning environments. It is classified under TSC style (Industry Standard Number TSC-8) and is intended for boring applications where a neutral, center-cutting geometry is required. The K21 carbide grade is suited for cutting cast iron, non-ferrous metals, and similar materials at moderate to high cutting speeds. The square shank profile seats securely in compatible tool holders without rotation under cutting loads.

Key Features

Compatibility

Designed as a standard-style replacement or stocking tool bit for lathes equipped with square shank boring bar holders accepting a 0.5 inch by 0.5 inch shank.

Installation Notes

Installation is performed by a machinist or tool setter. Before changing tool bits, power down the lathe and confirm the spindle has come to a full stop. Seat the square shank fully in the boring bar holder and tighten the set screw or clamping bolt to the holder manufacturer's specification before taking any cut. Inspect the carbide tip for cracks or chipping before each use, as a damaged tip can cause workpiece damage or tool failure during operation.
