Taps Types

1．Divided by application

Hand taps - usually rub alloy steel or high speed steel, Rolling molars made of relatively low accuracy, the general accuracy H4 Taps products, mainly used for hand-tapping, also can be used as a machine attack, but the cutting speed is lower, shorter life.

Machine Taps - high-speed steel (ordinary high-speed steel, high speed steel, powder metallurgy high speed steel sub) manufacturing, after heat treatment, molar from high precision, press H1/H2/H3 precision manufacturing machine cutting speed can be higher tapping, hand taps relative to longer life. Machine Taps carbide manufacturing Where applicable, the cutting speed can be higher and longer life.

Nut taps - commonly used alloy steel or high speed steel cutting the cone longer, oriented stable and smooth cutting, automatic tapping machine is mainly used for high-volume processing of all kinds of nuts.

Pipe thread taps - a cylindrical pipe thread taps tapered pipe thread taps divided, mainly used in various parts of the pipe fittings and pipe joints internal thread processing.

Broaching silk front - for the big pitch ordinary thread, trapezoidal thread, Square thread and ball screw threaded hole machining. Especially trapezoidal thread for processing, both broach with tap structure and operating characteristics.

2．Divided by function

Taps are divided into cutting tap and extrusion tap.

(1)Cutting tap the following three:
- Straight Flute Taps for through-hole and hole deep blind hole below 1.5d processing;
- Spiral Fluted Taps for blind holes and holes deep hole machining pass over 1.5d;
- The spiral point Taps for through holes, up to 3d to 4d.

(2) Extruding the taps have the following two:
- No sump extrusion tap;
- With sump extrusion tap.
