Carbide Tools

Produced under the guidelines of ISO 9000, the company says the E-Z Burr carbide tool can be run at speeds and feeds at least three times faster than regular high speed steel deburring tools. The titanium nitrate-coated carbide insert lasts more than three times as long as high speed steel inserts and blades, according to the company. The company says it is planning to maintain a stock of standard sizes from 0.250" (6.35 mm) through 1.0" (25.4 mm). Special orders can also be produced. The tools deburr or chamfer the front, the rear or both sides of a hole in a single pass by using a projected diameter greater than that of the hole and a retracted diameter equal to or less than the hole. As the rotating tool is fed into the piece to be worked, the extended blade/insert cuts the front burr, then immediately begins to collapse into a slot. When completely collapsed, the tool continues through the hole, not marking the bore in any manner. Once the tool has cleared the backside of the hole, the blade/insert springs out and cuts the rear burr as the tool is withdrawn. The blade/insert cuts and collapses until the tool is back inside the bore of the hole. The new carbide series features a locking system that is said to allow for the insert to be changed in seconds--without affecting the chamfer setting--while the tool is still in the machine.
