A tool life calculator can help you estimate the operating life of tools and components as accurately as possible. Engineering and machining calculators make it easier to precisely calculate the performance of almost any metal tool. From calculators for road rehabilitation equipment to applications such as slotting, milling, hole-making, thread cutting, and turning, here are seven reasons to calculate tool life.

Calculators help stakeholders take the most cost-effective approach to selecting tooling systems. Enter baseline carbide tooling information to determine the potential savings from using Road King Diamond Flex PCD tools compared to carbide in road rehabilitation applications.

## Slotting Calculators

Use slotting calculators to determine tangential force, torque and power or productivity based on adjusted feed and chip load. Select the most relevant slotting calculator for an application and convert Rockwell HRC or HRB into a Brinell hardness number. Slotting calculators refer to tool hardness along with ultimate strength, slot mill nomenclature and machining conditions.

## Milling Calculators

Kennametal offers several types of milling calculators. An end milling calculator for force, torque, and power is available as are two calculators for Kennametal Quick-Change Tooling systems. Calculators for G Spec Balance Formula and Helical Interpolation are also available.

Face Milling Calculators include a force, torque, and power calculator for these applications and productivity formulas for cutters with round inserts. For Z-Axis milling applications, you can use a force, torque, and power calculator or a Scallop Height Data calculator in Imperial or metric units.

## Holemaking Calculators

Calculate the operational demands and lifespan of hole-making tools, tap drill size, or D/H Limits for standard taps. Cutting fluid formulas for calculating velocity, power, flow and orifice size and tapping calculators are also useful for hole-making.

Calculate lead angle and shim selection for the LT Threading System with a Lead Angle and Shim Selection calculator.  To determine part numbers in the First Choice or application-specific catalogs, use the number 3 or 4 to indicate the measurement in place of the asterisk in results.

## Turning Calculators

Choose cutting forces, torque, and horsepower calculators for turning tools and applications. Calculators for boring bar deflection, cutting forces, and horsepower requirements are also available.

Other turning calculators determine time for face, cut-off or deep grooving and surface finish, inches per revolution, and corner radius. Most of these calculators require the Brinnell hardness number and have a converter for HRB or HRC.

## Speed and Feed Calculators

A general calculator for proper speed and feed in surface feet per minute, inches per minute, and rotations per minute is available under Miscellaneous Calculators. Choose a unit of measurement and enter the tool diameter and revolutions per minute to calculate SFM or RPM and feed in IPR to calculate IPM.

It is easy to make accurate tool life calculations when you use calculators relevant to your industry and a particular application. Using a calculator can help you anticipate the cost of maintaining equipment and replacing components to maintain efficient function and get more operating life out of every tool.
