Product Features

✅ Three Chuck Versions Available (A / B / C)

Version A – Universal drill chuck

• Clamping Range: 0.3 – 4 mm

• Accuracy: ~0.005 mm

• Best For: General use, wide bit selection

Version B – Fixed 3.175 mm chuck

• Clamping Range: 0.1 – 3.175 mm (shank 3.175 mm)

• Accuracy: ≤0.002 mm

• Best For: High precision, stable drilling

Version C – Three‑jaw chuck

• Clamping Range: 0.3 – 4 mm

• Accuracy: –

• Best For: Upgrade the 545 motor

Working Principle

• A DC motor (Version C uses 545 motor) drives the spindle through a precision brass sleeve.

• The chuck holds the drill bit firmly with low runout (≤0.002 mm for Version B).

• By adjusting the input voltage (3–12V), the motor speed changes continuously.

• The workpiece is placed on the fixed worktable; the spindle moves vertically along the 13 mm stroke to perform drilling.

This structure mimics industrial bench drills but at a micro scale, ensuring stability and repeatability.

Version A is a universal drill chuck with an accuracy of around 5 thousandths, capable of holding a wide range of sizes from 0.3 to 4mm. Version B is a fixed chuck with a 3.175-inch handle, suitable for drill bits with a 3.175-inch handle, with a high accuracy of within 2 thousandths. It is stable for drilling and is suitable for precision drilling purposes.

The fixed drill bit has a handle size ranging from 0.1 to 3.175, all being 3.175mm in length. Version C is a three-jaw chuck with a 3.3-4mm range, featuring a 545 motor. Dimensions are 100x80x180mm, with a column of 13mm, a drilling travel of 13mm, and the chuck to the worktable height being 70mm, with a net weight of 800 grams.

The drill stand is made of solid materials, with the main body being aluminum alloy. The spindle sleeve and the spindle use brass, and the workmanship is extremely fine. The parts are all CNC processed, and the part structure is made according to industrial-grade standards. The cost is not spared to create the most exquisite mechanical display item and craft collection for enthusiasts and collectors! The collection value is greater than the practical use.

The voltage ranges from 3 to 12V. Soft metals can drill holes up to 1 to 3mm. A 12V 2A adjustable power supply is provided, with adjustable speed. Micro Bench Drill 0.3-4mm Mini Drilling Machine Precision Watch Repair Tool Bench Drill With Speed Adjustable Power Adapter
