Product Advantages

NT SLN End Mill Holder adopts precision grinding taper handle (BT, CAT, HSK and other standards) to ensure high concentricity (usually ≤0.003mm) with machine tool spindle. The inner hole of the tool handle is treated by special technology to provide uniform clamping force, reduce tool jumping and improve the quality of the machined surface. The main body of the handle is made of high-quality alloy steel. After heat treatment and cryogenic treatment, the hardness is above HRC45 and the deformation resistance is strong. The Short Projection reduces the overhang and machining vibration, and is suitable for heavy cutting or machining high-hardness materials. Supports clamping straight shank end mills, drill bits, etc. Common clamping diameters range from φ 3 mm to φ 32 mm (specific models are optional). Adapt to a variety of tool holder specifications (such as BT30, BT40, CAT40, etc.) to meet different machine tool interface requirements. Side-fixed locking screw design (Set Screw) is convenient to install and firm to clamp, which supports quick tool change. Anti-rust treatment (such as oxidation or coating) on the surface can prolong the service life and is suitable for wet or dusty environment.

High Rigidity and Stability: tool holders secure tools with lateral screws, featuring a simple structure and high rigidity. They can withstand significant cutting forces, ensuring stability during machining.

High Precision: The contact surface between the tool holder and the tool is precision-machined, guaranteeing high coaxiality and repeatability, making it suitable for high-precision machining requirements.

Taper Specification:

The tool holder features a 7:24 taper, The taper precision meets the AT3 grade,

Bore Tolerance:

The bore tolerance of the tool holder is H5 grade, a precise tolerance level that ensures a high-precision fit between the tool and the holder, minimizing vibration and errors.

Dynamic Balance Grade:
At a rotational speed of 15,000 rpm, the tool holder achieves a dynamic balance grade of G6.3. This indicates excellent balance during high-speed rotation, effectively reducing vibration and ensuring stability and surface quality during machining.

Optional Accessories

The  tool holder is a versatile tool clamping device that can be flexibly equipped with various accessories, including U-drills, milling cutters, Tool locking device for NT, and pull studs, based on machining requirements. This design allows it to adapt to different machining tasks, offering greater flexibility and efficiency.
