Shrink chuck 4,5° with cooling channels HSK 63 - 03 - 120Application: For mounting tools with straight shanks. Note: Toolholders suitable for induction , contact and hot air shrink units. 3, 4, 5 with h4 tolerance and 6 32 with h6 tolerance For 3, 4 and 5 mm only solid carbide tool shanks must be used! All holders are made of forged steel Specific, low warpage hardened Surface hardened HRC 58~60 Hardening depth 0,8mm~0,9mm Taper angle tolerance < AT 3 according to DIN 2080 Surface roughness Ra < 0,4 m

For highest axial and radial loading

sleeves and tool arbors

Hardening depth 0

Improves chip evacuation and decreases the risk for chip jamming

For the manufacturing of special tools

In machining centres (machines with automatic tool changers)

driving ring and feather key

For face machining

In this way

• runout accuracy: = 0

For mounting straight-shank tools and inclined flat according to DIN 1835 form E (Whistle Notch)

For safe clamping of taps
