MT3 Keyless Drill Chuck, 1/8" - 5/8" Self-tightening Drill Chuck，3-16mm Heavy Duty Chucks with Spanner Wrench, Integral Shank, Titanium-Coated Jaws

SPECIFICATION- Clamping Range: 1/8" – 5/8" (3 – 16 mm)- Shank Type: MT3 Integral Shank- Run-out Accuracy: ≤ 0.002″ (0.005″ max, ±0.0025″)- Jaw Coating: Titanium-coated- Jaw Count: 3- Material: 20CrMnTiPACKAGE1*MT3 Keyless Drill Chuck1*Spanner WrenchMT3 Keyless Drill Chuck—1/8″-5/8″ (3-16 mm) all-in-one grip, MT3 integral shank drops straight in with zero adapters; ≤0.002″ run-out delivers tool-room accuracy; self-tightening action grips harder as torque rises—no key, no slip; titanium-coated jaws triple wear life and laugh off heat; one-piece steel body kills vibration, keeps repeatability cycle after cycle. Swap bits in seconds, drill after drill, year after year—precision, speed, endurance in one solid chuck.

• Grip Range: 3 – 16 mm (⅛″ – ⅝″), one chuck handles every common job-bit size. Solid MT3 integral shank provides instant plug-in stability
• Accuracy: ≤ 0.05 mm (0.002″) total run-out – high-precision bearings and ground jaws give drill-after-drill hole quality
• Self-Tightening Advantage: The harder the torque, the tighter the grip – no key, no slip, no downtime
• Titanium-Coated Jaws: TiN surface triples wear resistance, fights high temperature
• Integrated Body: One-piece steel body cancels vibration, maintains 0.002″ repeatability even under heavy cut loads
