These simple hand drills are an ancient, perfect design for drilling very tiny holes with minimal fuss. Simple to use, just press down on the top with a fingertip while working the bushing up and down the spiral screw shaft.
Available in two styles. The first, in solid brass, is 4-1/2" long and holds bits from 0.040" to 0.060" in its collet. The second is also solid brass, nickel plated, and is a little longer at 7-1/2". It has two collets with a capacity from almost 0 to about 0.055".
The drills (not listed here) range from 0.014 to 0.055". Five sizes (.014", .027" .035", .047" & .055") are available in a packs of two each size.
Made in India.
