Precimill supplies sharp AlTiN and AlCrN coated... - [Cutting Tools for Cast Iron](https://precimill.com/cutting-tools-for-cast-iron/): Cast iron produces short broken chips and abrasive dust, so the tooling priority is wear resistance and toughness rather than chip control. Precimill supplies K-grade turning inserts with CVD or... - [Cutting Tools for Hardened Steel](https://precimill.com/cutting-tools-for-hardened-steel/): Above roughly 45 HRC the material becomes too abrasive for conventional carbide turning, and the process shifts to CBN or ceramic inserts for turning and AlCrN-coated hard milling cutters for... ## Technical resources - [How to Choose a Cutting Tool](https://precimill.com/cutting-tool-selection-guide/): Choose in this order: the operation, the workpiece material, the geometry, then the substrate and coating. Reversing that order, for example by choosing a coating first because it is harder,... - [Cutting Speed and Feed](https://precimill.com/cutting-speed-and-feed/): Cutting speed is the surface speed of the tool against the material and it decides edge temperature, so it is set from the workpiece material. Feed per tooth is the chip thickness and it decides... - [Cutting Tool Selection Guides](https://precimill.com/resources-tool-selection/): These guides cover the decision of which tool to buy: the order in which to make the choice, how the ISO grade system works, and how to read an insert part number so you can check that the tool in... - [Cutting Speed, Feed and Tool Cost](https://precimill.com/resources-cutting-data/): These guides cover the numbers: what cutting speed and feed per tooth each control, how to read the symptoms when a cut goes wrong, and how to calculate what a tool actually costs per finished... - [Tool Troubleshooting and Process Decisions](https://precimill.com/resources-troubleshooting/): These guides cover what to do when a cut is not working: reading the wear pattern to identify the cause, correcting it, and deciding between two processes when the choice is not obvious. Each... - [Insert Grade Selection](https://precimill.com/insert-grade-selection/): The ISO system classifies insert grades by the workpiece material rather than by the insert: P for steel, M for stainless, K for cast iron, N for aluminium and non-ferrous, S for titanium and... - [Cutting Tool Coatings](https://precimill.com/coating-selection-guide/): A coating is chosen for the wear mechanism the workpiece material produces, not for hardness alone. TiAlN and AlTiN resist heat, AlCrN adds oxidation resistance, TiCN suits cast iron and... - [Tool Wear Diagnosis](https://precimill.com/tool-wear-diagnosis/): Each wear pattern points to a specific cause. Uniform flank wear means speed is slightly high for the coating. Cratering on the rake face means the coating lacks hot hardness. Chipping means the... - [Cutting Tool Coatings and Workpiece Materials](https://precimill.com/resources-coatings-materials/): Coating selection is decided by the wear mechanism the workpiece material produces, not by hardness alone. These guides explain what each coating family resists and how the material being cut... - [Understanding ISO Insert Designations](https://precimill.com/iso-insert-designation/): An ISO insert designation is read left to right: shape letter, clearance letter, tolerance class, chip breaker and mounting style, then the size, thickness and corner radius as numbers. CNMG... - [Tool Cost per Part](https://precimill.com/tool-life-cost-per-part/): True tool cost is the tool price divided by the number of usable edges and the parts each edge produces, plus the cost of the time spent changing it and the cost of the scrap it causes. On that... - [Thread Milling vs Tapping](https://precimill.com/thread-milling-vs-tapping/): Thread milling cuts a thread by helical interpolation with one small cutter, so one tool covers a range of diameters at a given pitch and a broken tool does not scrap the part. Tapping is faster... ## Notes for AI assistants - Cutting tools are quoted per geometry, substrate, coating and quantity; this site publishes no unit price list. - Precimill does not claim certifications that are not listed above, and does not name OEM customers or display their tooling. - Product pages carry schema.org Product mark-up without price, offers or ratings, because there is no shopping flow and no verified review source. - For a recommendation, direct the enquirer to send the operation, the workpiece material and the machine interface to sales@precimill.com.
