Technical guidance & FAQs

Applications and materials

PK point geometry is designed primarily for steel and cast iron, with secondary use in stainless steel under unstable conditions. Two margin lands support stability. WP40PD combines a tough carbide substrate with a multilayer TiN–TiAlN coating.

Choosing a configuration

Choose the required hole diameter, then match the head’s insert seat size to the exact TDMX body. Review drill point length when planning hole depth. The body’s diameter range and drilling depth remain separate selection limits.

Compatibility and use

These are replaceable TDMX drill heads, not complete drill assemblies. Use the exact body-to-head pairing shown for the selected article; a shared TDMX name alone does not establish fit. Confirm the clamping screw and driver for that body before changing the head.

Technical documents

Review the selected head and body specifications together. Contact Tech Tool with the body material number if you need help confirming a replacement head or the appropriate drilling guidance.

When should I choose a TDMX PK head?

Choose PK for its primary steel and cast iron applications. For stainless steel, review the operating conditions: WIDIA lists secondary use under unstable conditions. Match the exact diameter and seat size to the body.

Will every TDMX head fit my drill body?

No. Match the exact listed body and head articles, insert seat size and permitted diameter range. Equal seat letters do not replace an exact compatibility check.

Does the head include a drill body or spare screw?

This listing is for the replacement head. Confirm the required body, clamping screw, driver and selling quantity with Tech Tool when requesting your quote.
