Tool Bits

Tool bits are non-rotary cutting tools used in metalworking on compatible metal lathes, shapers, and planers. This category includes carbide-tipped tool bits and a replaceable carbide insert for common machining work such as turning, threading, cutoff and grooving, side cutting, and operations requiring square or pointed nose profiles.

How to Choose Tool Bits for Your Machining Setup

Select a tool bit by first matching the cutting operation and required profile, then confirm the listed style and any stated fitment details for your compatible machine tool or toolholder. The available options are stationary, non-rotary tools for metal lathes, shapers, and planers, with carbide-tipped choices across multiple tool forms.

Use Cases

Match the tool to the cut

Choose threading tool bits for threading work, cutoff and grooving bits for controlled cutoffs or groove formation, and turning bits where a square shoulder profile is needed.

How to Choose

Verify profile and style

Compare the required tool form, such as square nose, square shoulder, pointed nose, offset side cutting, or threading. Then match the listed style, including C-12, AR-8, CTR-44, E-series, GR-8, or D-8.

Applications

For stationary metalworking cuts

These non-rotary cutting tools are intended for compatible metal lathes, shapers, and planers used in metalworking operations.

Additional Info

Consider insert compatibility

The indexable E-6 threading tool bit lists a 3/8 in. square shank and 1/4 in. insert I.C. The TPG-321 option is a replaceable TiN-coated carbide insert for a larger tipped tool with a shank made from another material.

3Compatible machine types

Representative tool bits are intended for metal lathes, shapers, and planers.

5Cutting forms

Examples include square nose, square shoulder, cutoff and grooving, offset side cutting, and pointed nose.

7Threading styles

Threading options include E-6, E-8, E-10, E-12, and E-16 styles, with both carbide-tipped and indexable examples.

2Carbide tip grades

The represented carbide-tipped tool bits include C-2 and C-6 grades.

Planning Guide

Plan the right fit before choosing

Start With the Operation

Choose a cutting configuration that fits the work

Tool-bit forms in this category are organized around distinct metalworking operations. A profile designed for one operation may not match another, so begin with the cutting task required by your setup.

  • Square nose tool bits support work requiring a square nose profile.
  • Square shoulder turning tool bits support turning operations requiring a square shoulder form.
  • Cutoff and grooving tool bits support controlled cutting and groove formation.
  • Threading tool bits support threading operations on compatible machine tools.
  • Offset side-cutting and pointed-nose options address work requiring those specific tool forms.
Match Your Tooling Details

Use style designations and stated dimensions to narrow the selection

Style is a key comparison point across these tool bits. Available designations include C-12, AR-8, CTR-44, GR-8, D-8, and E-6, E-8, E-10, E-12, and E-16 threading styles. Where dimensions are stated, match them to the compatible toolholder or insert requirement.

  • Select the specified style required for the machining setup.
  • For the E-6 indexable threading tool bit, confirm the 3/8 in. square shank requirement.
  • For that same indexable tool bit, confirm compatibility with a 1/4 in. insert I.C.
  • Choose a replaceable insert when the tooling calls for the TPG-321 C-6 style.
Compare Carbide-Tipped Bits and Inserts

Understand the available cutting-edge formats

Most represented products are carbide-tipped tool bits with C-6 or C-2 carbide tips. The category also includes a TiN-coated carbide insert designed to provide the cutting tip for a larger tipped tool using a shank made from another material.

  • C-6 carbide-tipped options are represented in square nose, square shoulder, and multiple threading forms.
  • C-2 carbide-tipped options are represented in cutoff and grooving, offset side cutting, and pointed-nose forms.
  • The TPG-321 is identified as a TiN-coated carbide insert with a replaceable insert design.
FAQ

Common questions before buying

What machines are these tool bits used with?

Representative tool bits are non-rotary cutting tools for compatible metal lathes, shapers, and planers.

What is the difference between C-2 and C-6 tool bits?

C-2 and C-6 identify the carbide tip grades listed among the represented carbide-tipped tool bits. Match the grade and tool form specified for your operation.

Which tool bits are intended for threading?

Threading options include E-6, E-8, E-10, E-12, and E-16 style tool bits, including an E-6 indexable threading tool bit.

Is a carbide insert available?

Yes. The TPG-321 C-6 is a TiN-coated, replaceable carbide insert for a larger tipped tool with a shank made from another material.
