Drill chuck KREATOR KRT014004 1.5–13 mm, 1/2-20UNF threaded mount

Keyed drill chuck KREATOR KRT014004 accepts drill bits from 1.5 to 13 mm and uses a 1/2-20UNF threaded mount. This metal chuck is intended for mounting on compatible hand drills, drill drivers and rotary tools that accept this standard thread. The keyed tightening mechanism ensures firm clamping of straight-shank bits for general drilling tasks in wood, metal and plastics, and is suitable as a replacement or upgrade when the tool requires a 1/2-20UNF interface and the 1.5–13 mm capacity range.

Advantages

The chuck provides a wide clamping range from 1.5 to 13 mm, covering small pilot drills up to medium-size bits. A keyed gear mechanism allows higher clamping torque compared with keyless models, reducing slippage during heavier drilling. The 1/2-20UNF threaded mount is a common industrial standard that enables secure attachment to drills with matching spindles. Construction from hardened steel components enhances wear resistance for longer service life under normal workshop use.

Suitable for

• Replacing a worn or damaged chuck on drills with a 1/2-20UNF spindle
• General-purpose drilling in wood, metal and plastic
• Workshops, DIY projects and light industrial applications
• Use with straight-shank twist drills and driver bits within 1.5–13 mm

Key specifications

• Clamping capacity: 1.5–13 mm
• Mount type: 1/2-20UNF threaded mount
• Chuck type: keyed three-jaw drill chuck
• Material: hardened steel components (body and jaws)
• Suitable bit shank: straight round shanks

How to use

Ensure the drill spindle and threaded mount are clean and free of debris before installation. Screw the chuck onto the tool spindle using the specified 1/2-20UNF thread until fully seated and tightened; if applicable, secure with any retaining screw or locking mechanism provided by the host tool. Open the jaws with the chuck key, insert the drill or driver bit to the required depth, and tighten the jaws by turning the key until the bit is firmly clamped. Confirm the bit is centered and secure before starting the tool, and check periodically during use to retighten if necessary.

Usage recommendations

Use the chuck with bits that match the 1.5–13 mm capacity and straight shanks. For best results, select a chuck key of the correct size and avoid over-torquing the key to prevent damage to jaws or bit shanks. When performing heavy or high-speed drilling in metal, ensure appropriate cutting speeds, lubrication and secure workpiece clamping to reduce wear on the chuck. Replace the chuck if jaws show excessive wear, runout, or if secure clamping can no longer be maintained.
