Material Classification and Specifications

Materials are categorized into seven main groups with subgroups, detailing types and hardness ranges (psi and HRC):

• Group 1: Steel – Structural, case hardening, unalloyed, alloyed, and heat-treatable steels (57,000 to 210,000 psi; up to 42.8 HRC).
• Group 2: Stainless Steel (Inox) – Austenitic (Series 3) and ferritic-martensitic (Series 4) with hardness below 34 HRC.
• Group 3: Cast Iron – Spheroidal graphite and malleable cast irons (up to 145,000 psi).
• Group 4: Titanium – Unalloyed and alloyed titanium materials.
• Group 5: Copper, Bronze, Brass – Differentiated by chip type and alloy composition.
• Group 6: Aluminium and Magnesium – Unalloyed and alloyed with silicon content distinctions.
• Group 7: Synthetic Materials – Thermoplastics and hard plastics.

International standards such as AISI are cross-referenced for material grades to aid correct tooling selection.

Tooling Use Tables

Two key tables guide tool selection:

• Drilling Use Table: Matches twist drills (with cobalt content and coatings like TiN) to material hardness and type, covering steels, stainless steels, cast irons, copper alloys, aluminum-magnesium alloys, and synthetics.
• Threading Use Table: Details taps for threading (Whitworth, UNC, UNF, NPT), specifying tool materials (mostly 5% cobalt or HSS), coatings, point types, and tolerance classes aligned with material properties.

Drill Types and Specifications

Various twist drills are described, including general purpose, split point, reduced shank, hard materials (cobalt 5%), and Morse taper shank drills. Key parameters include diameter, overall and flute lengths, number of flutes, material (HSS, cobalt), finish, point angle (118° or 135°), and pricing.

Operating Parameters for Drills

Feed rates (inch/rev) and cutting speeds (ft/min) are specified by drill diameter and material group. RPM calculation formula is provided: RPM = (Vc × 1000) / (π × diameter). Coatings and finishes such as Gold Finish and Bright Finish are noted for performance enhancement.

Threading Tools and Standards

Comprehensive data on threading taps and dies for Unified Thread Standard (UNC, UNF, UNEF, NPT) and Whitworth standards are included. Tools are made from HSS and cobalt-enhanced HSS, with specifications on thread counts, cutting lengths, shank types, flute designs, cutting speeds, and tolerance classes (e.g., 2A, 2B). Pricing and product references are detailed.

End Mills and Milling Tools

The catalogue covers roughing and finishing end mills with various flute counts, helix angles, coatings (PMX, TiAlN-Top, TiAlSiN, cobalt 8%), and lengths. Feed per tooth (fz) and cutting speeds (Vc) are provided for different material groups. Tools conform to ASME standards with specified tolerances. RPM and feed velocity formulas are included to optimize machining parameters.

Material Groups and Cutting Parameters

Materials are grouped numerically to guide cutting speeds and feeds for drills, taps, and end mills. Coatings and tool materials are matched to material hardness and machining conditions to maximize tool life and performance.

Measurement Conversion and Symbol Index

Conversion tables between fractional inches, millimeters, and decimal equivalents facilitate accurate dimension referencing. A comprehensive symbol index standardizes tool use, characteristics, and material compatibility, supporting clear communication.

Materials and Coatings Specifications

Steel grades (M-2, M-35, ASP, M-42) and coatings (TiN, TiAlN, TiAlSiN) are detailed with chemical compositions, hardness, oxidation resistance, friction coefficients, and color codes. TiAlSiN is highlighted for dry machining suitability.

Best Practices and Recommendations

• Select tool material and coating based on workpiece material and hardness.
• Use recommended feed rates and cutting speeds to optimize tool life and machining quality.
• Apply correction factors in feed rate calculations depending on tool geometry and machining conditions.
• Choose appropriate drill length, shank type, and point geometry for application requirements.
• Follow DIN and ASME standards for threading and milling tools to ensure compatibility and quality.
• Reduce feed rates by 50% for long series or when drilling with end mills to extend tool life.

Ordering and Customer Support

Detailed product references, article numbers, and pricing in euros facilitate ordering. Contact information for commercial and technical support is provided, including email, phone, fax, and company location in Spain.

Summary

This technical catalogue from Izartool offers a comprehensive guide for selecting and using cutting tools—twist drills, threading taps and dies, and end mills—based on detailed material classifications, tool specifications, machining parameters, and international standards. It supports efficient, precise manufacturing with emphasis on quality, innovation, and customer service.
