Yamawa spiral tap for medium hardness carbon steel MHSP P4 M8X1.25

[Features]● A BLF shape is used at the rear of the fully threaded part to improve the blade chipping prevention effect of the fully threaded part. ●The overall length can be set to provide an appropriate tool overhang to avoid chips from interfering with the holder. ●The special shape of the threaded portion is effective in preventing blade chipping on the complete thread, reducing tapping torque and abrasion resistance, and maintaining screw guiding performance. ●To prevent chips from interfering with the holder, the overall length is set to ensure an appropriate tool overhang.

[Use] ● For drilling blind holes. ●For high carbon steel (S50C) and alloy steel (SCM440) (hardness up to 35 HRC). ● S48C to S55C forgings and tempered materials (hardness up to 35HRC)
