Drill Chuck PRO 13 mm 1/2-20UNF keyless (blister) EATM5UWB

Drill Chuck PRO 13 mm 1/2-20UNF keyless (blister) EATM5UWB is a keyless metal drill chuck designed for portable drills and drill drivers with a 1/2-20UNF spindle. It accepts round and hex-shanked bits with a maximum diameter of 13 mm and enables tool-free bit changes to improve workflow when alternating between drilling tasks in metal, wood and composite materials. The product is supplied in blister packaging for retail display and immediate use.

Advantages

The keyless design allows quick and safe bit changes without the need for a key or additional tools. A 13 mm capacity covers a wide range of common drill bit sizes for general-purpose drilling. The 1/2-20UNF threaded mount provides compatibility with many portable drills and drivers that use a standard half-inch threaded spindle. Durable metal construction ensures stable clamping and reliable bit retention during typical drilling operations.

• General metal drilling where frequent bit changes are required
• Woodworking tasks with various drill and screwdriver bits
• On-site and portable drilling with cordless or corded drills that have 1/2-20UNF spindle threads
• Applications requiring quick exchange between drilling and driving bits

How to use

Ensure your drill or driver is switched off and, if cordless, remove the battery before changing the chuck or bits. Hold the chuck sleeve and rotate to open the jaws to accommodate the desired bit, insert the shank fully and tighten the jaws by hand until the bit is securely clamped. Verify the bit is centered and firmly held before reattaching power. For heavy-duty or high-torque tasks, recheck tightness periodically during use to maintain secure retention.

Usage recommendations

Use the chuck within its 13 mm capacity and match the threaded mount to the tool spindle. Avoid overtightening by hand to prevent damage to bit shanks; for prolonged high-torque applications consider a keyed chuck or appropriate driving accessories. Regularly inspect and clean the jaws to remove debris and maintain secure clamping performance.
