CiirjjiiJy Tiijj wtlh ft r High hardened material Epoch Super Hard Tap for 50-60HRC Hitachi Tool Engineering, Ltd.

Stably machines tempered materials with hardnesses of 50HRC or more! One-shot machining after heat treatment reduces machining process. Cross-section shape minimizes torque during cutting. Cross-section design minimizes torque during cutting. Chips are broken up finely, so chip clogging is avoided. TH coating with excellent heat and wear resistance TH coating with good results on end mills is fine-tuned specifically for taps. Employs a 1-rank larger shaft diameter. In order to withstand the severe conditions when tapping high-hardness steel, the taps are designed with a larger-diameter shank...

Reverse-rotation cutting tooth shape The majority of tap breakage or chipping occurs when the tap is reversely rotated. During reverse rotation, not only is the direction of torque becomes reversed and loads placed on the tap, but also clogging of the teeth by chips is more likely, leading to breakage and chipping. Epoch Hard Taps are equipped with reverse-rotation cutting tooth shape to reduce the load during reverse rotation and minimize tooth clogging by chips, enabling stable tapping. No tooth clogging by chips during reverse rotation, enabling stable machining. Forward rotation During reverse...

1. Cautions regarding handling (1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands. 2. Cautions regarding mounting (1) Before use, check the outside appearance of the tool for scratches, cracks, etc. and that it is firmly mounted in the collet chuck, etc. (2) If abnormal chattering, etc. occurs during use, stop the machine Immediately and remove the...
