FAQs

What are the Accu-Tapper’s minimum and maximum tap sizes?

• 0-80 to 1/4-20 in steel
• 0-80 to 5/16-18 in aluminum & other soft metals
• 0-80 to 3/4-10 in plastic

Can it perform other operations besides tapping?

• Along with tapping, the Accu-Tapper has proven to be very effective at chasing threads, chamfering, reaming, deburring, OD threading/chasing and thread gauging.

How does the Accu-Tapper operate?

• The Accu-Tapper is equipped with a friction clutch between two 5″ pulleys. A 1/3 HP motor and standard V-belt keep the pulleys constantly rotating. When pressure is applied to the chuck, the clutch engages the back pulley, which begins spindle rotation.
• Rotation continues until pressure is released, causing the friction clutch to engage the front pulley, which reverses spindle rotation.

Is the Accu-Tapper user friendly?

• It takes the average operator 12 minutes to feel comfortable with the machine.

How do you adjust the torque for small holes?

• You never have to adjust the torque (or belt or a lead screw). The Accu-Tapper’s horizontal design and friction clutch makes the machine extremely sensitive. The smaller the tap, the lighter you push; the larger the tap, the harder you push. This design gives the operator complete control and feel of every part, making tap breakage virtually non-existent.

How does the machine work on round and odd-shaped parts?

• The Accu-Tapper’s guide plate has six drilled and tapped holes. This allows a variety of fixtures and jigs to be mounted on the front to support these types of parts.

How does the Accu-Tapper work on blind holes?

• The Accu-Tapper cuts the same high quality thread, whether the part has a blind or through hole. The adjustable slide under the chuck can be set in position for the same depth on every part.

What advantages does the Accu-Tapper have over a tapping head/drill press?

• The Accu-Tapper requires no permanent fixturing.
• The Accu-Tapper will greatly reduce tap breakage, compared to any other method.
• The Accu-Tapper is portable and self-contained, allowing it to operate anywhere without any additional equipment.
• The Accu-Tapper’s horizontal design is ideal for tapping extrusion, rods and other long parts.
• The Accu-Tapper requires virtually no maintenance. The user can quickly do any maintenance that might be needed. 

What are the advantages of tapping on the Accu-Tapper instead of the CNC?

• The Accu-Tapper takes the small hole tapping off the machining center, allowing it to perform more crucial work like boring, slotting and milling.
• The Accu-Tapper helps extend the life of the CNC. Tapping is one of the most demanding operations a machine can do.
• The Accu-Tapper reduces down time and scrapped parts, due to tap breakage.
• The Accu-Tapper allows the machine operator to perform secondary operations during cycle time.
