Precision drill chuck ER collect
Material: SUJ2 (high carbon bearing steel: after heat treatment,
has toughness and toughness, better wear resistance, and longer
elasticity and longer service life) · Hardness: HRC46° · Surface
roughness Rz2.5 The inner and inner holes are subjected to strict
honing processing and concentricity according to the DIN 6499
standard. There are three kinds of precision grades. S grade
0.015mm, grade A 0.01mm and UP grade 0.005mm·UP grade are
recommended for use with HSP nuts. Better stability · Used for
clamping drills, wire taps, milling cutters, reamers, etc. · With
elastic shrinkage, wide application range
Application:
gripping drills, taps, milling cutters, cutters, etc.
It has the function of elastic contraction, wide application range
and rich variability.
Usage:
holding drills, wire taps, milling cutters, reamer, etc.
Function:
elastic shrinkage, wide application range, and variability
