Titanium Nitride-Coated Custom Dies from CH4D

CH4D custom Titanitum Nitride dieNeed a custom full-length sizing die? Want something very special that will be gentle on your brass, reduce sizing effort, not rust, and never wear out? Tool-maker CH Tool & Die,, offers custom sizing dies, with optional Titanitum Nitride (TiN) coatings inside and out. Internal die dimensions can be set from fired brass you supply, a chamber cast, or specifications you provide (which could be based on a reamer print, with the dimensions tightened up slightly). Cost for a custom sizer die is $80-$130, depending on chambering (common calibers cost less). TiN coating adds to the price. Add $36.50 for the TiN die body, $10.80 for TiN expander ball.

CH4D custom FL dies are conventional full-length sizers without bushings. If you need to vary the neck tension, have the die spec’d for “normal” tension and then use a separate bushing neck-sizer when you need more tension. Normal turn-around time for a CH4D custom die is 10-12 weeks; TiN coating can add 2-3 weeks to that.

CH4D’s Dave Davison explains: “Titanium Nitride coatings have been used in industry for many years, primarily to extend the life of carbide tools. It has not been useful in reloading until recent advances in technology permitted TiN coating a die without softening the steel of the die itself. A TiN coated sizer in 308 Win showed no measurable wear after sizing 50,000 rounds. Although Titanium Nitride is harder than carbide and has a lower coefficient of friction it does not eliminate the need for lubricant when full-length sizing cases. It does reduce sizing effort considerably and minimizes the lubricant required. TiN-coated dies will live longer and require less force to operate than any die available. If you ever manage to wear out your TiN coated die, we will replace it at no charge. All we ask is that you tell us how many rounds you’ve loaded with it.”

CH4D can coat other manufacturers’ dies with Titanium Nitride. However, CH4D cautions: “TiN coating other manufacturers’ dies can be done, and is usually successful. However we have no control over the material or heat treatment of these dies and cannot guarantee the results.”
