Spring steel design: Expand your machining capabilities with our high-performance CAT40 collet chuck and ER spring-loaded collet chucks, offering exceptional balance and long service life. Includes 6 x CAT40 SLN collet chucks in the following sizes: 1/4", 3/8", 1/2", 5/8", 3/4", 1"; ER32 and ER16 dynamic balance collet chucks with an impressive 2.76" extension length; APU collet chuck with a 13 mm extension length; and a 1"-2.06" FMB collet chuck.
Perfected precision: Our CAT40 spring collets have a TIR of 0.0006 in / 15 μm, ensuring maximum precision. They are perfectly hardened and ground to guarantee excellent concentricity. These high-speed collet chucks are balanced to meet all industry standards, providing stable performance and are widely used in aerospace, automotive, medical device, electronics, and various other industries.
High-quality materials: Our CAT40 collet chucks and ER spring collet chucks are made of robust 40Cr or 45# alloy steel, hardened and precision ground, making them suitable for high-speed milling of precision parts, high-strength grinding, and various other machining scenarios. This also ensures the durability of the collet chucks and effectively combats deformation problems during machining.
Versatile Collet Sizes: Our collet chuck set includes 10 x ER16 collets in the following sizes: 1/32", 1/16", 3/32", 1/8", 3/16", 7/32", 1/4", 5/16", 11/32", 3/8" and 12 x ER32 collets in the following sizes: 1/8", 3/16", 7/32", 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4". The unique angled slots increase rigidity and provide an overall better balance for the collet chuck assembly. It is designed for use with any standard ER collet chuck and is ideal for coolant tooling applications.
Additional wrenches and pull studs: Our CAT40 collet set comes with 3 wrenches (ER32, ER16A, APU13) for extra tightening and easy loosening when needed. Ten pull studs are also included. Perfect for CNC lathes/milling machines, drills, and heavy-duty hand tools.
35-piece CAT40 collet holder and ER16/32 collet chuck set
We offer 4 types of collet chucks (SLN, FMB, ER16, ER32), 10 x ER16 collet chucks, 12 x ER32 collet chucks, 10 x drawbars, and 3 x wrenches. This comprehensive CAT40 collet set is made of alloy steel.
When high-speed milling of precision parts, the stability of your collet is of paramount importance. Our CAT40 collet holders and ER collet chucks are hardened and precision ground to ensure a rock-solid grip on your workpieces.
Our CAT40 collet holders and ER collet chucks are manufactured with high precision, which significantly reduces machining errors and scrap rates.
With individually labeled storage boxes for each collet chuck, you can easily select and place them, keeping your workspace tidy and your workflow efficient.
Our collet chucks feature a polished surface, which not only increases precision but also improves corrosion resistance. This ensures stable performance even in humid environments and provides a longer service life.
