Somma Tool Company has bench top machines for both tapping and re-tapping operations.

Somma's Tapping Machine, part number STC-TAP-ER, has a double disc friction drive which reverses rotation instantly by the application of forward or backward hand pressure on the part being tapped. The friction discs are driven by a Heavy Duty Tapered Cone Drive Collar mounted on the motor shaft. The machine has a 1/2" capacity chuck and the maximum spindle speed is 300 RPM. Tapping capacity is up to 5/16-18 thread in 1/2" steel. The machine has a work table that can be reversed when not needed and has an adjustable & removable "V" plate to hold small parts. The tapered spindle cone assembly, part number BB-TAP-6, is long lasting and it is also available as a spare part when needed.

Somma's Re-Tapping Machine, part number BB-SR, also has a double disc friction drive which reverses rotation instantly by the application of forward or backward hand pressure on the part being re-tapped. The BB-SR can retap threaded parts, chase threads, remove cutoff burrs from threads, inspect threads, countersink holes,deburr holes , and ream holes. The friction discs are driven by a Rubber Drive Ring mounted on the motor shaft. The RPM varies depending on the hand pressure exerted and the operation performed. The machine has a 1/2" capacity chuck and the maximum spindle speed is 1,000 RPM.The drive rings are long lasting and are also available as spare parts in two styles: part number BB-7 is made of black neoprene rubber and BB-7HD is more heavy duty and is made of orange urethane.

Both machines are rugged construction yet light weight and portable.
