Carbide Thread Mill UNC UNF NPT BSPT G

BB Carbide Thread Milling Cutter

NPT stands for National (American) Pipe Thread. It is the American standard for 60 degree taper Pipe threads.

BSP:
BSPT(PT, RC), short for Pipe Thread, is a 55-degree sealed tapered Pipe Thread.Commonly used in water and gas pipe industry.
BSPP（Parallel）(G, PS , RP),Straight cylindrical pipe thread.
G1/2-14=G3/4-14

New Blade Design It is not Easy to Collapse the Cutter and the Chip is More Stable

Smooth surface, not easy to collapse angle, taking into account the rigidity of the tool and chip removal performance, making cutting chip more stable
Three Blades，Four Blades

Fully Ground Cutting Edge Smooth Cutting Wear-Resistant and Durable

Sharp and no burrs, strong tool wear resistance, higher thread accuracy

Standard Pitch Can Pass or Stop

Wide applicability to precision tolerance standards

Micro Particles Solid Carbide

The use of micro-particle tungsten steel base material has higher wear resistance and stability,Exclusive milling cutter for high hardness, high speed cutting applications

More General Grade for Aluminum Steel

4 kinds of materials, can be applied to aluminum lamp soft material and steel parts and other hard materials

Thread Milling Principle

Thread milling is completed in a three-axis linked machine tool (machining center). When x and y axes go G03/G02 for one turn, the Z axis moves synchronously by the amount of pitch P
Machining Internal Thread
Machining External Thread

Remarks

Significance of 1/4-28 UNF
1/4 is the major diameter (outer diameter) of the thread, calculated in inches, 1 inch = 25.4mm
28 means that there are 28 threads per inch, which specifies the pitch.
UNF is United Fine Thread, that is, Fine Thread made in the United States, and some are UNC,C refers to coarse, that is, coarse Thread
