HOW THE RITMAR MIDGET CHUCK ELIMINATES THE TOUGH DRILLING PROBLEMS...

THE COLLET A slotted collet, internally drilled and punched to the desired drill size, is provided with a hexagonal head and external threads. Drill is inserted through the rear of the collet. The flutes of the drill are gripped by a pair of internal prongs in the collet head freezing the drill in place and preventing slippage. Collets will hold drill sizes from #50 to "F"...and fractional sizes from 1/16" to 1/4" by 64ths.

THE ADAPTER A goblet shaped piece having internal threads which mate with the collet threads. It also has an externally threaded shank which screws into the driving unit spindle. When the tapered shank of the collet is screwed into the internal bevel of the adapter, a squeezing action develops a vice-like grip on the drill preventing accidental extraction of the drill from the chuck assembly. Adapter threads fit four standard spindle sizes: #10-31;1/4"-28;9/32"-40;5/16"-24.

Both of these parts are made from steel bar stock, hardened and permanently coated with a rust preventive.
