Collet ER32 Ø11 mm for shank 10 mm DIN6499 — FORTIS

ER32 Ø11 mm collet for 10 mm shank according to DIN 6499 from FORTIS is a precision clamping element engineered to hold cutting tools with an 11 mm tool shank bore while mating to a 10 mm tool shank. Designed for use in ER32 collet chucks and toolholders, it provides concentric clamping and repeatable positioning for milling, drilling and general machining operations that require accurate retention of tooling.

Advantages

This FORTIS ER32 collet delivers precise radial runout control and stable axial hold in ER32 systems, helping maintain tool concentricity during high-speed rotation. The collet’s hardened and ground surfaces offer wear resistance and consistent clamping force over repeated tool changes. Compliance with DIN 6499 dimensions ensures compatibility with standard ER32 chucks and toolholders, enabling straightforward installation and interchangeability.

Suitable for

• CNC milling of metals and non-ferrous materials
• Drilling and reaming operations in machine tools
• General metalworking and workshop machining
• Tool setups requiring ER32 collet retention with 11 mm bore

Key specifications

• Collet type: ER32
• Bore diameter: 11 mm
• Intended shank compatibility: 10 mm shank tools (per DIN 6499 fit)
• Standard: DIN 6499 dimensional compliance
• Material and finish: hardened and ground clamping surfaces for durability

How to use

Insert the collet into a compatible ER32 collet nut or chuck, seat the tool shank into the collet bore and tighten the nut to the manufacturer’s recommended torque. Ensure the tool shank is clean and free of burrs before insertion to achieve correct seating and optimal concentricity. After tightening, verify runout and tool projection to confirm proper installation before commencing machining.

Usage recommendations

For best performance, use with chucks and holders that meet ER32 standards, avoid overtightening which can deform the collet or tool shank, and perform regular inspection for wear or damage. Clean the collet and tool shank before each change to maintain clamping accuracy and extend service life.
