Self Tightening Keyless Drill Chuck with Integral Arbor — KLD-13-R8

A self-tightening keyless drill chuck is a type of chuck that grips a drill bit automatically without the need for a key. The gripping force increases with the load, preventing the bit from slipping during operation.

An integral arbor means the chuck and the arbor (the part that fits into the machine spindle) are a single, solid piece. This design offers higher rigidity, better concentricity, and reduced vibration compared to a separate chuck and arbor, resulting in a runout accuracy of ≤ 0.05 mm.

The chuck body is constructed from hardened alloy steel for durability and longevity, while the jaws are made of precision-hardened steel to ensure a consistent and secure grip under high-torque industrial applications.

Yes, its robust construction and precise grip make it ideal for general-purpose drilling applications on both metal and wood.

We offer a range of models compatible with R8, ISO30/NT30, BT40, and ISO40/NT40 spindles, making them suitable for a wide variety of drill presses and milling machines.

The KLD-13-R8 is ideal for users with R8 spindle machines who require a clamping capacity up to 13mm. It's a great choice for small to medium-duty drilling tasks in workshops and fabrication shops looking for precision at an affordable price.

Choose the KLD-16-R8 if you have an R8 spindle machine and need to handle larger drill bits up to 16mm. It provides extra capacity for more demanding applications while maintaining the quick-change convenience of a keyless chuck.

The KLD-13-ISO30 is designed for milling machines and drill presses with an ISO30/NT30 spindle. It's perfect for users who need a reliable 13mm capacity chuck with the stability and precision of an integral ISO taper shank.

This model is the right choice for operators of ISO30/NT30 machines who need to drill larger holes up to 16mm. It combines the larger capacity with the robust, integrated shank for heavy-duty performance.

The KLD-13-BT40 is tailored for modern CNC machining centers and mills that use a BT40 spindle. It offers a 13mm capacity and the high precision (≤ 0.05 mm runout) required for CNC applications.

Select the KLD-13-ISO40 for heavy-duty drilling on machines with an ISO40/NT40 spindle. It provides a secure 13mm clamping capacity for industrial applications requiring high torque and stability.

The KLD-16-ISO40 is our top-tier model for heavy industrial use on ISO40/NT40 spindle machines. With a 16mm capacity, it's built for the most demanding drilling tasks where maximum grip and power are essential.

This model is perfect for CNC machining applications using a BT40 spindle that require drilling holes up to 16mm. It delivers the highest level of performance, capacity, and precision for demanding production environments.

The primary difference is the maximum drill bit shank size they can hold. The 13mm models are suitable for most standard drilling tasks, while the 16mm models provide the ability to use larger bits for heavy-duty applications and drilling larger diameter holes.

The choice depends entirely on your machine's spindle type. R8 shanks are common on manual milling machines like Bridgeport-style mills. ISO (or NT) and BT tapers are used on heavier milling machines and CNC machining centers. You must match the chuck's arbor to your machine's spindle.

For a typical small workshop with a drill press or a manual mill, the KLD-13-R8 model often provides the best balance of performance, 13mm capacity, and affordability. It delivers excellent precision and the convenience of a keyless design for a wide range of common tasks.
