Description
Product Overview
Swapping drills in and out of ER collets during a busy setup is tedious and time-consuming. For fast, highly rigid hole-making on your CNC mill, a premium keyless drill chuck is the ultimate solution. The Nikken BT40-NPU13-130 Drill Chuck is a top-tier Japanese toolholding solution engineered for massive gripping force and ultra-low runout.
- 1-13mm Capacity: The NPU13 chuck offers a highly versatile 1mm to 13mm holding range, accommodating your most common jobber and stub drills without ever needing to hunt down the correct collet size.
- 130mm Extended Reach: With a gauge length of 130mm, this extended toolholder is perfect for reaching down into deep pockets, clearing tall fixturing, or machining on large rotary tables where standard-length tooling would cause spindle interference.
- High-Torque Gripping: The self-tightening mechanics of the Nikken NPU series are legendary. You can easily snug your drills by hand for fast swaps, or use a standard C-spanner on the chuck body to lock the jaws down with immense gripping torque, completely preventing drill slip during heavy feed rates.
- BT40 / M16 Drawbar: Built on a rigid BT40 taper. The internal drawbar thread is the standard metric M16 size. It currently has a pull stud installed, meaning it is ready to drop straight into your spindle or tool carousel.
Condition
Used (Great Condition / Smooth Action).
This high-end Nikken toolholder is in great, fully functional used condition and has clearly been well cared for in a professional environment.
- The Jaws: The most critical part of any drill chuck is the jaws. The clamping jaws on this unit are in excellent shape, free of heavy scoring or spun-drill damage, ensuring a perfectly concentric grip on your cutting tools.
- Mechanical Integrity: The tightening collar rotates smoothly without any gritty binding. Cosmetically, the tool body shows typical minor handling marks and light surface patina expected from shop use.
