General Specification:
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.
