Sutton Tools VH / XH Taps

Product catalog summary

Overview: This document provides technical specifications and guidelines for using Sutton's carbide taps designed for tapping hardened steel. It includes product details, usage instructions, and a case study comparing Sutton's taps with a competitor's product.

Specifications:

Material: Specially developed carbide for extra toughness.
Coating: Optimised hard coating (TiCN).
Geometry: Specific geometry for hardened steel with special relief.
Applications: Suitable for machine operations, through and blind holes, with depths up to approximately 1.5 times the diameter.
Product Codes: T294, T295, T296, T297 with corresponding discount groups and material specifications.

Usage Guidelines:

Use neat cutting oil and remove chips/swarf after each tapped thread.
Set torque to high when using a tapping chuck with a torque clutch; prefer quick-change adapters without torque clutch.
For machine use only, not suitable for hand use.
Maximum thread depth is 1.5 times the diameter.
Speed values can be increased by approximately 10% when using machines with synchronized spindles and solid rigid holders.

Case Study:

Comparison of torque between Sutton VH Carbide Tap and a European competitor's tap.
Material: D2 (60HRC), Coating: TiCN, Lubrication: 7% water soluble.
Sutton VH showed lower average torque (340 Ncm) compared to the competitor (397 Ncm).

Formulas:

n = (vc × 1000) / (Ø × π)
vc = (Ø × π × n) / 1000
vf = f × n

Legend: n = revolutions per minute, vc = cutting speed (m/min), f = pitch (mm), vf = feed rate (mm/min).

Material Specifications:

Various materials listed with hardness, tensile strength, and recommended cutting speeds.
