Justace End Cap Reamers

It is a reamer dedicated to inner diameter machining holes that do not penetrate such as end caps. By shortening the center guide of the Just Ace original reamer as much as possible, it is possible to process the inner diameter of unpenetrated holes, which could not be processed with a grip reamer. The method of use is the same as that of the grip reamer. The feature is the "center guide" at the end of the reamer. Align the outer diameter of the center guide with the inner diameter of the grip to be machined, and when rotated straight, it passes through the center of the grip and the inner diameter is machined at the blade part. Instead of pushing the reamer forcefully, gently push it in as if you are slowly scraping it with the tip of the reamer blade while rotating it. The inner diameter can be processed without blurring the center, and the finish is very beautiful. The mounting part is machined on a hexagonal shaft for the hexagonal shaft chuck so that it can be done manually. Of course, it can also be used for keyless chucks. size [RME12-15] Center guide: 12mm / Inner diameter: 15mm / Length: 150mm [RME12-17] Center guide: 12mm / Inner diameter: 17mm / Length: 150mm [ Precautions when using electric equipment (drills, etc.)] ■ Never touch the reamer while spinning. ■ The reamer after work is very hot due to friction. Please do not touch it. ■ Do not use for any purpose other than drilling. ■ When working, please wear appropriate clothing and use protective equipment such as safety glasses. ■ When using the drill chuck, make sure that the chuck is tight before use. ■ When starting and turning, be careful not to get caught in electrical cords, clothes, etc. ■ Do not rotate at high speed at first, but gradually increase the speed while checking the rotation slowly. ■ If the reamer is pressed too hard, it will not be processed cleanly. It can be processed with a light reamer blade. ■ Do not apply strong force or use at an unreasonable angle. It may be damaged. ■ Do not use impact drivers. ■ Please do not engage in any other dangerous acts.
