THERMAL SHRINK CHUCKING SYSTEMS SHRINKIN thermal shrinking collets are an enhancement to the existing popular ER collet system. The SHRINKIN collets utilize the thermal expansion and shrink phenomenon for rigidclamping of steel, HSS and solid carbide tools. SHRINKIN collets provide high torque, precision runout and excellent repeatability. The SHRINKIN ER collets with their slim design and various projection lengths allow the user to reach deep cavities and perform narrow milling applications. Ingersoll offers a complete system for the SHRINKIN collets with integral ER or other standard, integral tapered shanks. The conventional, thermal shrink chucking unit can be used only for solid carbide tools, clamped into SRK ER collets. The induction thermal unit can be used for steel, HSS and solid carbide tools. It can be used for both SRK and SRKIN collets with ER or other integral tapered shanks. T.I.R.
