This became very evident with Coldspring’s diamond tooling needs. Coldspring could get the tools they needed, but due to shipping timelines from over- seas, it was often too big of a hold up for their production. In their case, delivery was key. This ultimately drove them to lean on their own trades, and be able to develop what was needed in house. “Whether its equipment or diamond tooling, we’ve built a lot of our own tools,” continued Massmann. “I guess you could say we started out doing it more for our own use, rather than be- ing able to sell it to the rest of the industry.”
New Directions
By the 1980s, Coldspring had built a larger tooling facility headed up by Linus Dingman, specifically to produce diamond tools using an improved electro- plating technique. At the time, sintered tooling was still all the rage, but being industry pioneers, the folks at Coldspring took an additional route and began build- ing tooling using an electroplat- ing process that used a small electrically charged plating tank of warm chemicals. With this sys- tem they could produce tooling where the diamonds were bonded with a nickel coating, the first be- ing their T-31 Anchor Bits.
Success was on the horizon, and as the popularity increased for electroplated tooling, Coldspring

continued to move forward to supply demand. Bigger plating tanks and better ways of process- ing were needed to satisfy the growing market for more diverse and larger tooling, continued Massmann. “In the early 1990s, we started doing more types of tools. That’s when the countertop market really got going, and we developed a lot of tooling with different profiles. We also did a lot of custom profile tools in those days.”
According to Massmann, the Coldspring facility currently houses eight plating tanks – in- cluding some that can handle electroplating of very large sized pieces. “We have the capability to do large calibration wheels that are eight to ten feet of solid steel. We’re coating that entire piece of steel with diamonds in

Custom Sintered and Electroplated Tooling: A Coldspring Specialty
Coldspring manufactures tools for a wide range of applications such as cutting, milling, heavy stock removal, coring, drilling and edging. CNC tools come in Half- Gas or 35 mm, while saw blades run from four inch to enormous.
Precision manufacturing to precise specs is the hallmark of Coldspring tooling. Below: a large scale custom milling drum.
Coldspring builds blades and seg- ments for blades up to 138 inches in diameter (11 feet-6 inches).
Like any other tool manufactur- er, Coldspring has a standard line of tooling with a replacement or money-back guarantee. However, unlike other tool manufactur- ers, Coldspring will work with the customer to build any custom tool to their needs or specs, said Massmann.
“We have a standard line of seg- ments that we put on our blades, but we also customize segments. Every week we are customizing
a segment, and modifying if it’s a regular solid segment, or if it’s what we call a layered (sandwich) segment, where there’s a different mix on the outside versus the in- side. Turnaround time for custom tools is one to two weeks, while modified, standard tooling can be out the door in one to two days.
“We work with the customer from the very start, understanding their equipment, the RPMs and all the parameters that their equip- ment can run, as well as what ma- terial they are working with.
