• Adjustable chuck typically accepts bits up to 1/2"

• Smooth gear-driven mechanism provides consistent rotation

• Ideal for use in metalworking, woodworking, and construction

• Often features a side handle for better grip and balance

• Fully manual operation – no electricity required

Specifications (may vary by model):

• Chuck Size: 1/4" to 1/2" capacity

• Material: Cast iron or steel body with wood or plastic handles

• Gear Ratio: Commonly 2:1 or 3:1 for faster bit rotation

• Breast Plate: Contoured or padded for comfort and pressure distribution

Common Uses:

• Drilling holes in tough materials where electric tools aren’t practical

• Field work where power access is limited

• Precision work in metal fabrication or traditional woodworking
