Features 1、The chuck is composed of a main body and a tapping socket. The main part has a front and rear pitch compensation device. The tapping clamp state has two types of overload protection and non-protection 2、Overload protection, when the chuck is tapped, just adjust the nut to obtain different slipping torsions to prevent the tap from breaking, which is convenient and quick 3、Wear-resistant and durable, tightly clamped with high stability 4、The tapping tool holder is easy to install and remove, and the operation is simple 5、With floating, telescopic and quick-change function, widely used in CNC machining centers, drilling machines, lathes, CNC/milling machines, boring machines and tapping machines, etc. Specification Item Type: Collet Chuck Holder Model: MT4-GT24-130L Material: High speed steel Tool Handle Hardness: 58-60 degrees Accuracy: 0.002mm to 0.008mm Purpose: Anti-overload protection, stop tap breakage Advantages: Anti-overload protection, the tap will automatically slip when reaching a certain torsion to prevent the tap from breaking; has the functions of floating, telescopic and quick-changing Function: Used for clamping straight shank taps, used for tapping processing Application: Used for tapping processing; widely used in CNC machining centers, drilling machines, lathes, CNC/milling machines, boring machines and tapping machine tools, etc. Tool Handle Length: Approx. 130mm / 5.1in Size of Chuck: Approx. 30mm / 1.2in Maximum Diameter of Tool Holder Taper: Approx. 30.02mm / 1.2in Applicable Chuck: GT24 TC324B G12 Interface Location: GT24 Size: Approx. 30mm / 1.2in Package List 1 x Collet Chuck Holder
