Overview

This document provides a detailed technical guide for selecting bandsaw blades—specifically bimetallic and tungsten carbide types—and cutting fluids for industrial metal cutting applications. It targets users working with a wide range of metals including aluminum, carbon steels, alloy steels, stainless steels, titanium, and nickel-based alloys.

1. Product Selection and Material Compatibility

Materials are categorized by machining difficulty, from easy to difficult, covering low/high carbon steels, alloy steels, bearing steels, tool steels, stainless steels, titanium alloys, and nickel-based superalloys (e.g., Inconel®). Blade product lines are ranked by cutting performance and durability, including:

• Qxp™: High yield, faster cutting.
• Contestor GT®: Superior yield for standard applications.
• Armor® Rx®+: Long life, suited for interrupted cuts.
• Lenox Rx®+: Ideal for profiles and bundles.
• Classic Pro™: Versatile with long life.

2. Blade Tooth Pitch and Geometry Selection

Guidelines recommend selecting tooth pitch (TPI or DPP) based on material shape (solid square/rectangular, round, tubular/profiles) and size (wall thickness or diameter). Finer tooth pitches are advised for single-piece cutting, while coarser pitches suit bundle cutting. Tables correlate dimensions in inches and millimeters with recommended tooth pitches for precise blade choice.

3. Bimetallic Blade Product Lines and Applications

• Armor® CT Black: High-performance with a hard, wear-resistant coating (aluminum, titanium, nitrogen).
• Lenox TNT CT®: Designed for difficult materials.
• Tri-Tech CT™: Set tooth design reduces blade binding on tough materials.
• Tri-Master®: Versatile for multiple materials.
• Cast Master™: Optimized for foundry materials.
• Lenox HRc®: Tungsten carbide blade for hardened materials with reinforced teeth and fatigue-resistant backing.
• Master-Grit®: Carbide-tipped for abrasive and treated materials with metallurgically bonded tungsten carbide particles.

4. Tungsten Carbide Blade Features and Tooth Design

Advanced tooth geometries such as VARI-TOOTH® and TUFF TOOTH™ provide smooth cuts, reduced vibration, and extended tool life. Tooth height and thickness options are matched to cutting dimensions. Special coatings like MERCURIZED and ALTIN ARMOR® improve heat resistance and wear protection by reducing thermal conductivity and protecting individual teeth. Blade backings use high-performance steel to resist deformation and fatigue under high stress.

5. Blade Performance and Cutting Recommendations

• Set tooth patterns (stradatura) prevent blade binding in highly stressed materials and are suitable for pivoting saw machines.
• Positive rake angles enhance cutting speed and blade longevity.
• Multi-chip tooth designs reduce vibration and cutting forces, improving manual feed operations.
• Special tooth profiles and sequences minimize noise and vibration, ensuring smooth, straight cuts even on multiple pieces or wide sections.

6. Cutting Fluids and Lubricants

• Lenox Lube®: Synthetic lubricant for spray applications.
• C/AI Lube®: High lubrication spray lubricant.
• BAND-ADE®: Semi-synthetic cutting fluid.

7. Support Services and Tools

• SAWCALC®: Online blade selection system tailored to cutting needs.
• GTO Performance Trials: Blade performance testing with money-back guarantee if unsatisfactory.
• Machine Optimization: Technical inspection of saws at 13 points to optimize blade and machine performance.
• Training Seminars: On-site operator training to improve efficiency and reduce downtime.
• Technical Support: Telephone assistance from professional technicians for blade selection and cutting advice.

Critical Parameters and Best Practices

• Choose blade tooth pitch based on material shape, size, and cutting method (single vs. bundle).
• Select blades with coatings and tooth designs suited to material hardness and abrasiveness.
• Use recommended cutting fluids to reduce heat and wear.
• Leverage technical support and training to optimize cutting processes and extend blade life.
• Consider blade backing strength and tooth set to prevent breakage and binding.
