High-Strength Drawbar / Tie Rod Model A0001 R8

High-Strength Alloy Steel Construction

Made from hardened and tempered alloy steel to withstand high clamping force and rotational loads.

Precision Threading

Machined threads ensure smooth tightening and secure engagement with R8, NT30, NT40, or other tool holders.

Heat-Treated for Durability

Provides improved wear resistance, longer service life, and stable performance under continuous operation.

Accurate Length for Perfect Fit

Manufactured to exact length specifications to match specific spindle types and milling machine models.

Smooth Surface Finish

Reduces friction during tightening and prevents damage to spindle threads.

Corrosion-Resistant Coating

Zinc-plated or black-oxide finish protects against rust and workshop humidity.

Easy Grip Head Design

Equipped with hex head, T-handle, or knurled head for easy tightening and loosening.

Stable Tool Clamping

Ensures firm locking of collets and tool holders, minimizing vibration during machining.

Compatible With Multiple Tool Holder Types

Available for R8, ISO30/NT30, ISO40/NT40 systems.

1. Securing collets, tool holders, and cutting tools in the spindle of vertical and turret milling machines.
2. Used in R8, NT30, NT40, and BT30 spindle systems for precise tool clamping.
3. Ensures stable operation during milling, drilling, and boring operations.
4. Essential for CNC and manual milling machines requiring accurate tool alignment.
5. Used in tool change operations for maintenance, refurbishment, or upgrading milling machines.
6. Provides reliable clamping for high-speed and heavy-duty machining applications.

The Draw Bar is a critical component used in milling machines to securely hold tool holders, collets, or cutting tools inside the spindle. It passes through the spindle from the top and tightens the collet or tool holder by pulling it upward, ensuring precise alignment and firm clamping during machining operations.

Designed for high-strength performance, draw bars are typically manufactured from hardened alloy steel to withstand high rotational forces, vibration, and repeated tightening cycles. The threaded end of the draw bar matches the specific collet or tool holder type—such as R8, NT30, NT40, BT30, etc.—ensuring compatibility with a wide range of milling machine models.
