Side fixed tool holder SLN/A tool holder BT40 CNC machining center

Overview

BT-SLN side lock tool holders are high-rigidity CNC holders for heavy-duty machining. Adopting rigid side screw clamping design, they provide stable high-torque cutting with zero tool slip, ideal for heavy roughing and long-overhang processing.

Key Features

Stable Heavy Cutting: Rigid locking structure prevents tool micro-slip under heavy load.
High Rigidity & Anti-vibration: Integrated forged body effectively reduces vibration for deep and long-reach machining.
Excellent Durability: Premium 20CrMnTi steel with vacuum heat treatment ensures high hardness and long service life.
Cost-effective: Collet-free design saves maintenance costs compared with standard ER holders.

Technical Parameters

Precision: ≤0.003mm (AA Grade) / ≤0.005mm (A Grade)
Dynamic Balance: G6.3 standard, G2.5 optional for high-speed machining
Multiple styles: DIN heavy-duty, JIS slim, internal/external cooling types

Applications

Suitable for mold roughing, U-drill drilling, deep cavity machining, stainless steel and titanium alloy heavy milling, long-reach boring. Not for ultra-precision finishing.

Basic Specifications

Taper: BT30 / BT40 / BT50
Clamping Range: 6mm–40mm
Length: 75L–200L, customized extended length available
