Solide carbide UN cutter taps

Carbide UN cutter taps

US thread (except for pipe) generally refers to a thread of a standard tooth type according to ANSI B1.1 with a crest angle of 60 degrees and parallel threads. The series of American threads refers to the combination of thread diameter and pitch. For US-made uniform threads, it refers to the number of different teeth per inch corresponding to a certain series of specific diameters, ie the number of teeth per inch.
The US thread series includes five series of UNC, UNF, UNEF, UN and UNS, which represent coarse teeth, fine teeth, superfine teeth, constant pitch and special threads. Among them, UNC and UNF are the most commonly used. The smaller outer diameter is indicated by the number: NO: 0, NO: 1, NO: 2, NO: 3, NO: 4, NO: 5 up to NO: 12, a total of 10 numbers; For example, 1/4-20UNC, 1/4 is the outer diameter size, 20 is the number of teeth per inch, and UNC is the coarse tooth in the US uniform thread.
The following are the specifications of the more commonly used American (non-pipe) thread taps (wire taps) U:
NO 0-80UNF, NO1-72UNF, NO 1-64UNC, NO 2-56UNC, NO 3-48UNC, NO 4-40UNC, NO 4-48UNF, NO 5-40UNC, NO 6-32UNC, NO 6-40UNF, NO 8-32UNC, NO 8-36UNC, NO 10-24UNC, NO 10-32UNF, NO 10-40UNS, NO 12-24UNC, NO 12-28UNF, NO 12-36UNS, 1/4-20UNC, 1/4-24UNS 1/4-28UNF, 1/4-32UNEF, 5/16-18UNC, 5/16-20UN, 5/16-24UNF, 5/16-27UNS, 5/16-32UNEF, 3/8-16UNC, 3 /8-20UN, 3/8-24UNF, 3/8-32UNEF, 7/16-14UNC, 7/16-20UNF, 7/16-24UNS, 7/16-28UNEF, 1/2-12 UNS, 1/2 -13UNC, 1/2-16UN, 1/2-20UNF, 1/2-28UNEF, 9/16-12UNC, 9/16-18UNF, 9/16-24UNEF, 5/8-11UNC, 5/8-18UNF , 5/8-24UNEF, 3/4-10UNC, 3/4-16UNF, 3/4-20UNEF, 3/4-24UNS, 7/8-14UNF, 7/8-20UNEF, 7/8-24UNS, 15 /16-28UN, 1"-8UNC, 1"-12UNF, 1"-20UNEF, 1-1/8-12UNF, 1-1/8-16UN, 1-1/4-7UNC, 1-1/4- 12UNF, 1-1/2-6UNC------ and so on.

Usually American or British threads do not directly mark the pitch, but mark how many teeth per inch, for example: 1/4-20, 20 means 20 teeth per inch, then the pitch should be: 25.4/20=1.27mm.

Features:
carbide Taps are usually divided into single or groups. The through-hole thread of the small and medium size can be tapped once with a single tap. When processing a blind hole or a large-sized screw hole, a group of taps is commonly used, that is, one screw hole is sequentially processed by using two or more taps. Group taps have equal and unequal diameters

Two designs. The carbide  taps of the equal-diameter design have different lengths of the cutting cones only; the carbide  taps of the unequal-diameter design have different thread sizes, and only the last one has a complete tooth shape.

Spiral-Pointed taps, or Machine Taps, were originated to solve the problem of tap breakage in through hole tapping. The Machine Tap shoots chips ahead of the cutting action, thus reducing loading and clogging in the flutes. They are recommended for use in through or blind holes which allow for chip accumulation in the bottom of the hole. Ideal for threading a wide variety of ductile materials, copper and copper alloys, brass and non-metallics.
