Product Introduction
Machine tool accessories er collet, All types of ER collets conform to the DIN 6499B Standard.Using quenched high-strength special materials, after cryogenic treatment, the product performance is stable, wear-resistant and durable.
Collet sets are available in metric and inch series, with complete models and specifications. You can choose a suitable set according to your needs. At the same time, it can meet the clamping of tools such as milling cutters, drills, and reamers of various specifications. It is easy to use and cost-effective.
The collet serves two purposes: to apply maximum clamping force to the tool and to maintain minimum overall runout.

ER systems have four main advantages:
The first advantage is that they are less prone to jamming. This is because they are even clamped meaning the rear can compress and be less likely to get stuck in the spindle taper.
The second advantage of the ER system is that it reduces wear vibrations and noise during operation. This is because even clamping produces a smaller overall runout.
The third advantage is that less torque is required on the spindle nut to get the correct clamping force on the tool. This reduces the likelihood of the tool being pulled out during operation.
The fourth and final advantage is that each collet can hold a range of tool diameters. For example, this collet is eight to seven, which means it can hold tools with a shank diameter from eight to seven millimeters.
