DISPOZABLADE – The ultimate solution for easy, accurate and economical planer and jointer knife changes.

For over 20 years ESTA-USA has focused on one single goal, to provide the woodworking industry as well as the part time woodworker with a planer and jointer knife that anyone can change accurately, quickly and economically. Unlike every other quick change planer knife system, our blades are designed to work in the ordinary cutter head of most machines found in today’s woodworking shops. The combination of these features in one simple knife is unique to woodworking tooling. Extensive research and development has resulted in a line of planer and jointer knives that have completely replaced the troublesome, frustrating and imprecise task of changing knives with a method that is simple, easy and accurate.

Each generation of DispozaBlade has progressively made changing knives easier while improving setting accuracy. First with the introduction of acu-set knife support screws in the mid 1980’s, then with Posi-Set knife support magnets in the mid 1990’s and now with the latest breakthrough in 2007, Self-Set® knife holders.

But common to each generation of DispozaBlade is the use of our time tested German quality double edge disposable knives. These High Speed and Kobalt steel knives are the trade standard for being more cost effective than conventional knives which require regrinding. The factory ground edges always provide peak machine performance and finish quality.

Whether using Posi-Set® or Self-Set® we can confidently:

“Today I installed a set of Dispozablades in my 50 to 60 year old Powermatic 60 jointer. After I cleaned out the blade slots in the cutter head, I installed the blades. They slid in without a hitch. I couldn’t figure out why they weren’t getting tight, until I remembered that I was tightening the gib screws instead of loosening them. Fixed that screw up, and the installation went perfectly. I had to loosen and lower the out feed about table approximately 3-5 thousandths. Once done, I checked the the blade fit, and they were dead on. I checked by measuring the movement of a straight edge ruler when contacting the blade as it was rotated past TDC. This is the second set of Dispozablades I’ve purchased and I couldn’t by happier. Excellent, First Rate Product.”–Burt Pierce

“The local resharpening cost had increased to the point that it was lower in cost to use the Dispozablade double-edged refills,” said Hill. “Combine this with the fact that it is not necessary to adjust the rear table when installing fresh blades after the original installation; both time and money are saved. The product works just as advertised and I think has a longer working life than my original equipment re-sharpened blades.”–Chuck Hill, of Hill Engineering Inc. Del Mar, CA.
