Questions about this product
- What materials and projects is this straight slot milling cutter best for?
- Use this tool for precise engraving, slotting, and making direct plunge cuts. It works exceptionally well for milling PCB isolation tracks and cutting keyways in aluminum, brass, or plastic. The straight two-flute design helps you mill clean channels with a smooth finish.
- Will these end mills fit my CNC machine or router spindle?
- Yes, as long as you match the shank size to your machine's collet. We offer these bits in four distinct shank diameters: 3.175mm, 4mm, 6mm, and 8mm. They work with most standard CNC engravers, mills, and precision router spindles.
- What is the recommended speed limit for running these carbide bits?
- We recommend operating these solid tungsten carbide bits between 12,000 and 30,000 RPM. Your optimal spindle speed depends on the cutting diameter and the specific material you are machining. Smaller bits generally perform better at the higher end of this RPM range.
