Tool selection & buying guides
Exactalloy product line overview: seven categories in one page
The catalogue is organised by machining task, so a workpiece and operation can be matched to a category before comparing individual SKUs.
Frequently asked questions about selecting and buying cutting tools
Short answers to the questions that most often block a purchase: which tool, which holder, what to send for a quotation and what happens after delivery.
Quotation, lead time and technical support: what to expect
Understand how a quotation is prepared, what typical lead times apply to stock, standard and custom items, and how technical support is arranged before and after an order.
Tool holder compatibility: what to check before choosing a chuck
A holder must match both the machine spindle and the cutting tool. Record the interface, size, bore, projection and required accessories before comparing hydraulic, shrink fit or collet systems.
Understanding displayed currencies and quantity price breaks
Compare prices for the same SKU, currency and quantity. The storefront converts a CNY base price for display, while checkout confirms the payable currency and final order total.
