BT-APU Drill Chuck Holder is an integrated tool holder combining shank and keyless drill chuck in one-piece structure with internal threaded design. Reduces connection errors and improves precision while preventing chuck head from falling off during heavy-duty and high-speed cutting operations. Designed for gripping drill bits and reamers only. Features self-locking function with dedicated APU wrench included. The integrated design shortens overall tool length, enhancing machining precision and extending tool service life. APU series offers 0.06 mm runout precision. For higher accuracy applications, ER or SK series are recommended. *Wrench and pull stud must be purchased separately
