Handy-Thread

General Information:

Thread Sizes: 

The Handy-Thread machine is ruggedly constructed, and fully adjustable in every way. The standard machine will cut or roll threads from 1/8" through 5/8" N.C., N.F., or 16mm with the proper chasers (one set for each thread lead).

Electrical Requirements: 

The standard non-reversing machine uses a 1-1/2 HP, 1725 RPM, 115 volt, 60 Hz, single-phase electric motor with 3-prong grounded plug. It should be plugged into a 3 prong grounded receptacle with 20-ampere capacity on 115 volts.

Compressed Air Supply: 

The standard machine requires a compressed air supply of 85 PSI minimum gauge pressure, with a flow capacity of about 1/2 SCFM (standard cubic feet per minute). If no compressed air is available in the plant, a small air compressor of 1/2 HP which will deliver at least 85 PSI should be adequate for most jobs. The compressor should be used with a receiver (storage tank) of 10 to 30 gallons capacity.

Cutting Fluid or Coolant: 

Modern chemistry is developing many new and improved cutting fluids. Contact your local supplier of cutting tools if you have no special source for purchasing cutting fluid. The fluid should have a viscosity of no higher than 200 SSU (rated at 100°F). A minimum of 5 quarts and a maximum of 8 quarts are required in the Handy-Thread reservoir. When filling the reservoir, pour the fluid into the chip pan it will drain through the chip screen into the reservoir. Caution! Do not mix cutting fluids of different kinds because of the possibility of forming gums which would clog the pump, the coolant tube, or die head. If the fluid discharge tube should become clogged it can usually be cleared with a blow gun without removing it from the machine. Blow backward through the tube. If necessary to remove it for cleaning, unscrew the pipe where it comes out of the machine base plate and pull the tube out. Caution! Running the pump without cutting fluid may damage it. If fluid is not desired for threading certain materials, turn the pump off with the selector switch on the electric control box. If the cutting fluid is too thick (viscosity too high), the pump may have difficulty in picking it up when the machine is first started and the fluid is cold. This may happen even with thinner fluids in cold weather. Caution! Do not use flammable or aromatic solvents to thin the cutting fluid because of the danger of fire.
