Description

Tighter Tolerances

These toolheads are made to the highest standards by Whidden Gunworks. All critical machining is done on one operation, yielding tolerances of 0.0002″ on all critical dimensions. This means that all die mounting holes are positioned precisely relative to each other and are exactly perpendicular to the flange. The flange is also flatter than possible with a cast toolhead. The 7/8″-14 die mounting threads are machined to Class 2B tolerance to mate better with the threads on your dies. This results in the dies being more accurately centred in each hole and reduce offset when tightening the die locknut.

6061-T6 Aluminum Alloy

The toolheads are machined from 6061-T6 aluminium alloy. The T6 tempering process yields an ultimate tensile strength of at least 42,000 psi. The result is a toolhead that is about 50% lighter than a cast toolhead, but also much stronger. These toolheads are thinner but have no voids or cavities on the bottom.

Clamped?

The Clamped toolheads mount with Grade 8 alloy screws that come with the toolhead. You can read more details about the benefits of clamped toolheads on the product page for the UniqueTek Toolhead Clamp Kit.

Take Control of OAL!

The UniqueTek Toolhead Clamp Kit enables the toolhead of Dillon 550 & 650 presses to be CLAMPED into the press frame. This corrects the loose fit between the toolhead and press frame, thus reducing OAL (overall length) variation and stabilising die-to-shellplate alignment. Your press frame remains unmodified so you can still use standard toolheads/die plates with the original toolhead pins and your original manufacturer’s warranty will not be affected.

Advantages

  • Eliminates Loose Toolhead-to-Frame Fit
  • Reduces OAL Variation
  • Improves Crimp Repeatability
  • Improves Bullet Concentricity from Seating Die
  • Reduces Jams at Size/Decap Die

Customer Feedback

“I am delighted with the 650 toolhead and have ordered them previously. Quality and precision are excellent. They are the only toolheads we use. No Dillon’s. We also use your powder baffles and look forward to trying more of your innovative products.” Best regards, Brian S. – Morocco, IN

“Having a machined tool head with the clamp kit installed sounded like something I wanted to try. I bought one tool head to test out, and I am very impressed with the results. I setup the tool head for 9mm loading, and the finished product is some the best ammunition I have loaded to date, and I’ve been rolling my own since 1958.”

“The one thing that has always bugged me is OAL variances of finished cartridge length. Using your tool head with clamp kit has dropped that variance to a very acceptable number. I loaded up 200 rounds and took a random 20 count sample for measurement. The variance was .001″ for the 20 rounds. As far as I’m concerned, it doesn’t get any better that that.”

“Thanks for offering us reloaders/shooters products that are not gimmicks, but are practical and affordable.”
Regards, — Tim F. – Mineral Wells, TX
