Threading Taps

Threading Taps manufactured by Industrial Machinery Corporation (IMC) are cutting tools used to produce internal female threads in pre-drilled or punched holes. The cutting edges remove material while the flutes provide chip space and help carry chips and cutting fluid away from the cutting zone.

Threading Taps Manufacture & Applications

• Internal threads in nuts and machined components
• Production and maintenance tapping
• Machine tapping on compatible internal threading equipment
• Metric and inch-series internal threads

How a Threading Tap Works

The tap enters a correctly sized prepared hole. The chamfered cutting section begins the thread and the following full threads size and finish the internal form. Correct tap-drill size, alignment, speed and lubrication are important for tap life and thread quality.

Available Thread Forms

The stored IMC information lists BSW, NPT, UNF, Metric, UNC, ACME and BSF thread forms. Final availability depends on nominal diameter, pitch/TPI, material and tap geometry.

Machine Tapping

For production tapping, see the Internal Threading Machine. Machine selection and tap selection should be reviewed together where repeatability and output are important.

Threading Tap Quotation Information

Send the thread standard, nominal diameter, pitch or TPI, hole material, through-hole or blind-hole requirement, usable thread depth and quantity.

tooling selection guide

Internal threading taps are selected for the thread form, hole condition and material being machined. Machine tapping tools need to suit the holder, cutting conditions and whether the hole is blind or through. Thread cutting taps should be specified using the standard, nominal size, pitch or TPI and required usable thread depth. Include these details with a sample or drawing so that the tool can be reviewed for the actual tapping operation.

Information to send with your enquiry

• thread standard and pitch
• blind or through hole
• usable thread depth
• material and hardness
• tool holder and production method

Provide a dimensioned drawing or a representative sample together with the intended daily quantity. Identify the features that must be held to a tolerance and the inspection method used for acceptance. Where several sizes will run on the same equipment, describe the smallest and largest job and how often changeovers are needed. This helps clarify the tooling and setup discussion before a quotation is prepared.

Configuration, inspection and support

Ask IMC to confirm the proposed model, included tooling and the scope of supply in the written quotation. Discuss inspection of a representative finished component and any acceptance requirements before ordering. Confirm installation needs, operator guidance, maintenance information, spare parts, warranty terms and after sales support for the configuration offered. Capacity, electrical supply, automation and delivery should be agreed for the actual job; do not infer an option solely from another model listed on this page.
