The 10mm Hand Drill Gear is the core transmission component inside electric hand drills. It transfers the motor's rotational power to the output spindle, ensuring smooth and efficient drilling performance. These gears are commonly manufactured from 20CrMnTi, 20MnCr5, 40Cr, SCM415, or SCM420 alloy steel, followed by carburizing, quenching, precision grinding, and heat treatment for excellent hardness, wear resistance, and long service life.
Product Features
Made of premium 20CrMnTi alloy steel for high strength and toughness.
Carburized and quenched for high surface hardness and excellent wear resistance.
Precision CNC machined for accurate tooth profiles and smooth transmission.
Stable gear meshing with low noise and reduced vibration.
High load capacity for demanding torque transmission.
High transmission efficiency with reduced power loss.
Excellent fatigue resistance for extended service life.
