Key Features

Sturdy and Durable: The product is made of high-quality S45C high-carbon steel, using tempering treatment technology, with high strength, wear resistance, high precision, and long service life.

Work Assistant: Round jaw (clamping size: 1.49-2.99 in) and interchangeable jaws of the big round jaw (clamping size: 2.75-4.25 in), pin jaw (clamping size: 0.19-1.69 in), and step jaw (clamping size: 0.19-1.69 in) handle a wide range of clamping types and diameters to meet your work requirements.

Powerful Grip: The chuck provides an incredible grip when manually locked and won't come loose easily, giving you more confidence in your use.

Easy to Use: With the T-wrench, you can hold the workpiece in alignment with one hand and use the wrench to control the clamping jaws with the other. It is different from other chucks that use metal rods to control jaw tension, making it easier and simpler to operate.

Thoughtful Design: The chuck is self-centered so that each jaw can be adjusted to the center position. When the knurled ring is rotated, the jaws move together so that the workpiece can be quickly clamped in place, enabling the clamping of most shapes of workpieces.

Good Adaptability: A 4" chuck body with M33 standard thread, and a 3/4 "x16Tpi adapter provide great convenience.

Convenient Storage & Carrying: You can easily store it in the notched organizer without taking up extra space and with easy access. The storage box with latch and handle also makes it easy to work on the go.

Effortless Cleaning: The smooth surface and simple structure allow you to easily remove dust from the surface of the product with a towel.

Nice Gift: This practical product is a great holiday or housewarming gift for family, friends, and those who love to do crafts so that they can enjoy a more convenient life.

Details

T-type Wrench: It is easily installed by simply inserting it into the hole in the face of the chuck and rotating it.

Round Corners: They protect your skin as you use and cleanse.

Application

This product can be applied to medium-sized or miniature lathe work, firewood turning, making bowls, woodworking, pens, and other clamping tools.
