DRILL POINT GRINDER CHUCK

Product Description

The 6-Jaw Chuck ZITHER/BONET is a high-precision workholding device designed specifically for drill point grinding machines. With six jaws working simultaneously, it offers even clamping pressure, making it ideal for holding thin-walled, fragile, or round tools like HSS and carbide drills.

Manufactured from hardened alloy steel, the chuck ensures long life, excellent concentricity ( 0.01 mm TIR), and repeatable accuracy. It is widely used in tool rooms, grinding shops, and precision machining environments.

Q1. What is the purpose of a 6-jaw chuck in a drill point grinder?

A: It provides uniform clamping of drill bits to ensure accurate point grinding without damaging the tool.

Q2. How is a 6-jaw chuck better than a 3-jaw chuck?

A: A 6-jaw chuck offers better grip and concentricity, especially for small-diameter or fragile tools, reducing deformation.

Q3. What sizes are available?

A: Common sizes include 80 mm, 100 mm, and 125 mm with clamping ranges from 1 mm to 25 mm.

Q4. Can it be used on CNC machines?

A: Yes, high-precision 6-jaw chucks are compatible with CNC tool & cutter grinders, depending on the mount type.

Q5. What material is used to make this chuck?

A: Typically made from hardened and ground alloy steel for wear resistance and durability.

Q6. What is the typical runout or TIR (Total Indicator Reading)?

A: High-precision 6-jaw chucks have a runout of 0.01 mm, ensuring excellent alignment during grinding.
