Heavy Duty SDS Plus Rotary Hammer to 13mm Keyed Drill Chuck Converter, Wood Spade & Metal Twist Bit Adaptor Kit (KC1301.1) | INGCO

INGCO 13mm Heavy-Duty Keyed Drill Chuck with SDS-Plus Adaptor Set (1.5-13mm Capacity, 1/2″-20 UNF Thread, Steel Toothed Key Included)

Instantly add high-precision wood and metal drilling capabilities to your heavy-duty rotary hammer drill. The INGCO KC1301.1 13mm Keyed Chuck Set eliminates the need to carry multiple heavy power tools to the construction site or workshop floor. By pairing a robust, all-metal 1/2″ keyed chuck with a quick-connect SDS-Plus adaptor shank, this conversion kit lets you drop standard straight-shank twist drill bits, masonry bits, spade cutters, and hole saws straight into your SDS-Plus rotary hammer—giving you maximum workspace versatility with rock-solid clamping security.

Industrial All-Metal Build & Universal Thread Platform

• Precision-Grip 1.5mm to 13mm Capacity: The adjustable 3-jaw system accommodates a massive array of accessories—tightening smoothly down onto tiny 1.5mm ($1/16\text{ Inch}$) micro-twist drills up to massive 13mm ($1/2\text{ Inch}$) heavy-duty straight-shank bits with concentric centering accuracy.

• Standard 1/2″-20 UNF Thread Connection: Machined with an industry-standard 1/2-inch diameter, 20 threads-per-inch (UNF) internal mounting port. This universal thread profile ensures perfect, wobble-free alignment when threading onto the included adaptor or standard corded/cordless drill spindles.

• Hardened Steel 3-Jaw Squeezing Grid: The internal gripping jaws are forged from high-density, heat-treated alloy steel. The jaws feature deep mechanical biting surfaces that anchor straight-shank bits completely rigid, entirely eliminating bit slippage during high-resistance metal and hardwood drilling runs.

Quick-Change Adaptor & Keyed Security

• Heavy-Duty SDS-Plus Adaptor Shank Included: Shipped out of the box with a premium, wear-resistant SDS-Plus drive adaptor. This allows you to snap the entire 13mm chuck sub-assembly straight into your heavy rotary hammer drill chuck in under two seconds.

• Solid Industrial Toothed Chuck Key: Includes a matching, thick-gauge steel chuck key. The keyed manual tightening configuration delivers up to three times the mechanical clamping torque of standard keyless chucks, ensuring your bits stay locked tight even under immense torsional resistance.

• Reverse-Thread Safety Locking Screw: Features an integrated internal left-handed thread security screw that locks the chuck tightly onto the adaptor shaft. This structural barrier completely prevents the chuck from unthreading or spinning loose when running your power tool in reverse gear mode.

Product Specifications:

Best Use Cases

• Rotary Hammer Drill Conversions: The absolute industry standard accessory for masonry contractors and electrical installers to rapidly switch a heavy SDS-Plus hammer drill over to run standard wood spade bits or high-speed steel (HSS) metal drill bits.

• Heavy Timber Framing & Carpentry Fabrication: Perfect for structural carpenters to run thick, straight-shank auger bits down through heavy wood columns and ceiling joints with total grip security.

• Automotive Maintenance & Workshop Bench Drilling: Ideal for garage mechanics to mount specialized polishing shafts, wire wheel brushes, and countersinks onto existing tool setups.

• Pencil Carving Art Studio & Display Layout Prep: An exceptional conversion asset for pencil carving artists to adapt larger drilling attachments, micro-sanding drums, or heavy mounting hardware buffers onto variable-speed bench systems with precise centering control.

TK Pro Tip: A keyed drill chuck is a magnificent high-torque mechanical tool, and utilizing all three key holes is the ultimate secret to achieving perfect concentricity and stopping bit slippage! When mounting a drill bit inside this 13mm chuck, never tighten the key in just one single hole. Instead, tighten the chuck loosely with your hand first, insert the toothed steel key into the first hole and tighten firmly, then rotate the chuck and repeat the tightening squeeze in the remaining two holes. This three-stage protocol distributes the internal mechanical pressure completely even across all three jaws, guaranteeing an absolute straight bit alignment and a non-slip lock. Additionally, always switch your rotary hammer drill over to “Drill Only” (Rotational) mode when using this adaptor set. Never run this chuck in “Hammer/Chipping” (Percussive) mode, as the violent back-and-forth concrete hammer impacts will stress the internal thread matrix and prematurely damage the locking screw!
