Ingco 13mm Professional Keyed Drill Chuck with SDS-Plus Adaptor and Key – Heavy-Duty Carbon Steel Jaw Conversion Kit for Rotary Hammers and Combi Drills (KC1301.1)

Converting a heavy-duty rotary hammer or an industrial impact drill to accept standard straight-shank twist drill bits, hole saws, or spade bits is impossible without a specialized conversion interface. Standard SDS-Plus chuck systems are built exclusively for grooved masonry bits, leaving wood and metal drilling accessories incompatible. The Ingco KC1301.1 13mm Professional Keyed Drill Chuck with SDS-Plus Adaptor is an all-in-one chuck conversion solution engineered to bring maximum tooling versatility to your power tool fleet. Featuring a robust 1.5mm to 13mm gripping range and a pre-assembled threaded adapter shank, this premium workshop accessory allows structural builders, metal fabricators, carpenters, and electrical installers to instantly switch from heavy concrete hammering to high-precision wood and metal boring using a single power tool.

The exceptional clamping strength and high rotational accuracy of this conversion set rely on its drop-forged, heat-treated carbon steel gear ring and matching chuck key. The precision-machined three-jaw matrix advances uniformly when tightened with the included key, delivering a uniform, non-slip grip around round or hexagonal shanks to prevent tool spin under extreme loading. Outfitted with a standard 1/2" x 20 UNF internal thread specification, the chuck body comes paired with a premium SDS-Plus adapter rod and a reverse-thread locking screw. This security screw locks the adapter tightly to the core spindle, preventing the chuck from spinning loose or unscrewing when running the drill in reverse mode during tricky bit extractions.

Key Features

• Universal 1.5mm – 13mm Capacity – Expands your tool's capabilities by holding a massive variety of standard straight-shank wood bits, metal HSS bits, and diamond hole saws.

• SDS-Plus Shank Adaptor Included – Drops directly into industrial rotary hammer drills, instantly converting a percussive masonry tool into a precise rotary-only drill.

• High-Torque Keyed Tightening – Classic keyed configuration maximizes gripping torque on the bit shank, completely eliminating slip during heavy metal or hardwood drilling.

• Anti-Loosening Reverse Lock Screw – Features a left-hand threaded internal safety screw that anchors the chuck to the adapter, ensuring safe operation in both forward and reverse.

• Industrial Hardened Steel Build – Drop-forged gear sleeve and induction-hardened jaws resist teeth deformation and friction wear over long workshop lifespans.

• Branded Color Box Layout Pack – Securely packed inside an iconic, heavy-duty Ingco color box to protect the precision chuck threads and keys from warehouse dust.
