Product Details

Spiral fluted tap  is a tool for thread processing. The utility model belongs to a kind of tap, which is named for its screw discharge groove. Spiral groove taps are divided into left spiral groove taps and right spiral groove taps. The geometric parameters of spiral groove tap mainly retain helical angle, chip groove, front angle and rear angle. Spiral groove tap has the advantages of long service life, high efficiency and low cost, good cooling and lubrication conditions, smooth cutting, easy buckling and low torque. Spiral groove tap is one of the most commonly used taps. Different helical angles are adopted according to different working conditions. The common spiral angles are right-handed 15 degrees and 42 degrees. Generally speaking, the lar ger the helix angle, the better the chip removal performance. It is suitable for blind hole processing. It’s better not to use through hole processing

Features:
Excellent 6542 high speed steel, high hardness with good durability.
Titanium coated surface for anti-rust.
Performed well in tapping, quick with high accuracy.
Suitable for processing metals with hardness below HRC 30°.

Instructions:
(1) When tapping, first insert the cone head so that the center line of the tap is consistent with the center line of the drill.
(2) Rotate evenly and apply a little pressure to feed the taps. No additional pressure is required after the feed.
(3) Each turning tap is inverted by about 45° at a time to cut the chips to avoid clogging.
(4) If the tap is difficult to rotate, do not increase the rotational force, otherwise the tap will break.
