Horizontal Hold Down Action (HTC-Series):
The holding action in these types of Toggle Clamps is same as VTC-Series clamps. The outstanding characteristic is the low height design. Unlike the handle & the clamping bar of the VTC-Series, these of the H-Series clamps move in opposite direction. The holding capacities range upto 1,000 kgs. The clamping arm can be solid bar, U shaped or fixed hole type.
The SF Series have solid hold down bar which has a fixed guide bush at its end for the spindle assembly.
The SB Series have a "U" bar arm which the bolt retainer can be welded at any desired angle.
The UB Series have a "U" bar arm which enables one or more spindles to be moved into any desired position along the arm.

1. What is an ER40 spanner used for?An ER40 spanner is used to tighten and loosen ER40 collet nuts, which hold cutting tools securely in CNC machine spindles. It ensures proper torque application without damaging the nut or tool holder.
2. Are all ER40 spanners compatible with ER40 nuts?Most ER40 spanners are compatible with standard ER40 collet nuts. However, if you are using a mini or special nut (like ER40M), check the compatibility, as some spanners are designed for specific nut profiles.
3. What materials are ER40 spanners made from?ER40 spanners are usually manufactured from high-quality hardened steel or alloy steel. These materials provide excellent strength and durability, making the spanner suitable for frequent industrial use.
4. How do I use an ER40 spanner safely on a collet nut?Turn off the machine, hold the tool holder steady, and use the ER40 spanner to tighten or loosen the collet nut. Apply firm, even pressure—avoid over-tightening to prevent damage to the nut or collet.
5. Can I use a single ER40 spanner for different ER series nuts?No, ER spanners are size-specific. An ER40 spanner is designed exclusively for ER40 collet nuts. Using it on ER32, ER25, or smaller/larger sizes may result in improper grip and tool damage.

1. What is an ER40 collet?
An ER40 collet is a precision tool-holding device used in CNC machines, designed to securely grip round-shank tools like drills, reamers, and end mills. It belongs to the ER (Extended Range) collet system, known for its wide clamping range and high concentricity. ER40 collets are larger in size and are ideal for holding tools with larger diameters, typically ranging from 3mm up to 26mm.
2. What is the max size ER40?
The maximum clamping size of an ER40 collet is 26mm, depending on the specific collet in the set. Each collet also has a collapse range of approximately 0.9mm, meaning a 26mm ER40 collet can clamp tools from 26mm to about 25.1mm securely.
3. What does ER20 collet mean?
An ER20 collet is a medium-sized collet in the ER series, used to hold cutting tools with diameters ranging from 1mm to 13mm. The "ER" stands for Extended Range, indicating its flexibility in clamping different tool sizes. ER20 collets are commonly used in CNC milling, tapping, and drilling applications, offering precision, vibration control, and compatibility with a wide variety of tool holders.
