* Manufactured from imported High speed steel.
* Uniform heat treatment for required hardness as per Rockwell C scale.
* High tensile strength ensures longer life.
* Available in size 4=" x 2=" x >",8 or10 TPI V or U-profile 55.
NCT SINGLE ANGLE CUTTERS for helical milling of segments/rolls are made with M 15 steel (synonymous to VG Steel), a tough grade which gives longer life to the tool even when worked on stainless steel.
NCT cutters, size 3" X 5/8" X 1.1/4" are available with 55, 60, 62, 65, 68, 70 LH & RH angles with appropriate tool geometry. They are spacially designed to cut stainless steel with minimum cutting loads. This ensures longer tool life.
NCT CHASERS for chasing grooves in segments/rolls are also made from M 15 steel and manufactured to the exacting standards required by the Tea Industry. These are available with 6TPI,8 TPI or 10 TPI in"U" and "V" profiles.
Optimum combination of microstructure, grain size and hardness are ensured in heat treatment for durable performance. On specific demand, cutter / chasers are also made from AISI M-2 / M-35 / M-42 and others HSS grades of customer’s choice.

Your tapping requirement may be unique for various reasons, but one common requirement in all applications is successful tapping. Some examples of why your application may be special...

material characteristic such as swarf type, elasticity, strength and hardness. depth of hole thread size pitch thread form reach holding

There are essentially four qualities in successfully designing and manufacturing a tap...

theoretical knowledge and practical experience are intrinsic in this process.

Base material, its heat treatment, and final surface coating are significant factors; but they would be irrelevant without the correct geometry. Tap geometry involves a combination of features tailored to all the above... thread and flute cutting angles, flute pattern, cutting force reduction features. The culmination of these geometrical features is the knowledge we refer to. Our knowledge combined with processes and equipment, allow consideration of all these variables.
