Main Product Description
Klein T118.985.R is the exact right-hand ER32 variant in the T118 family of HSK63E collet chucks. The official Item row specifies a nominal A-dimension of 76 mm, 50 mm body diameter, 63 mm HSK flange diameter, 2–20 mm ER32 clamping range, and right-hand rotation.
The holder is supplied with the Z091.001.R standard clamping nut and is intended for Klein T119 ER32 spring collets, which are sold separately. The threaded nut system follows DIN 6499, while the HSK hollow taper is produced to DIN 69893 and includes provision for a Balluff microchip.
Klein specifies balancing to 24,000 RPM and a maximum concentricity error of 0.003 mm between the conical interface and the tool seat. The stated A-dimension is measured with a clamped tool shank and may vary depending on the diameter of the installed tool.

Before Machining
Compatibility & Installation Notes
Confirm the exact T118.985.R Item code, HSK63E spindle interface, right-hand rotation, ER32 collet size, 2–20 mm tool-shank range, clamping-nut condition, collet seating, tool projection, and machine speed limits before use. The Z091.001.R nut is included, but the T119 ER32 collet is sold separately. The nominal A-dimension can vary with the diameter of the clamped tool.
Production Outcome
Precision HSK63E ER32 Toolholding
Klein T118.985.R combines an HSK63E interface, ER32 clamping from 2 to 20 mm, right-hand rotation, 24,000 RPM balancing, and a maximum stated concentricity error of 0.003 mm.
Correct spindle fit, collet and nut selection, tool-shank engagement, projection, rotation, cleanliness, and machine parameters are essential to achieving the intended holding accuracy and operating performance.
