Description
Product Overview
The HanOaki drilling holder is engineered for demanding industrial and scientific applications where precision, durability, and efficiency are non‑negotiable. Constructed from hardened steel that undergoes a special quenching and hardening treatment, the holder resists wear even under continuous high‑speed drilling. Its three‑claw design provides a zero‑gap, tight lock on drill bits, eliminating slippage and maintaining exact spindle alignment. Dimensions measure 6.3 x 2.36 x 2.36 inches and the unit weighs 1.83 pounds, offering a compact footprint without sacrificing rigidity. Integrated into the holder is a self‑tightening mechanism that automatically secures the bit as the spindle rotates, cutting changeover time dramatically.
Usage
Designed for CNC machining centers, milling machines, and high‑precision drilling rigs, this holder excels in aerospace component fabrication, automotive part production, and heavy‑duty metalworking. Its robust construction tolerates the high torque and rapid feed rates typical of modern manufacturing floors. Technicians appreciate the quick‑release feature that allows rapid bit swaps during multi‑operation runs, reducing machine idle time. The holder is also suitable for research labs that require repeatable drilling accuracy for prototype development.

FAQ
What size drill bits are compatible with this holder?
The holder accommodates standard metric and imperial drill bits ranging from 1 mm to 13 mm in diameter, covering most CNC machining applications.
How does the self‑tightening mechanism work?
When the spindle reaches operating speed, the built‑in cam engages the three claws, pulling them inward to clamp the bit securely without manual adjustment.
Can the holder be used on both vertical and horizontal machining centers?
Yes, its compact geometry and balanced weight allow installation on vertical, horizontal, and universal machining platforms.
Is any special maintenance required?
Regular cleaning of debris and periodic lubrication of the cam surfaces are recommended to maintain optimal performance; no additional adjustments are needed.
What warranty does HanOaki provide?
HanOaki offers a one‑year limited warranty covering material defects and workmanship, backed by a dedicated technical support line.
