Types of cutting tools: Single-point cutting tools can be classified by their motion as linear or rotator‚ depending on whether they rotate while cutting. Linear cutting tools include tool bits (single-point cutting tools and broaches. Rotary cutting tools include drill bits‚ countersink and counter bores‚ taps and dies milling cutters and reamers. Other cutting tools‚ such as band saw blades and fly cutters‚ combine aspect of linear and rotary motion. Following are different types of cutting tools:

Coolant and cutting fluid management Contamination of coolants and loss of cutting fluid through chip waste is one of the most time consuming and costly situations for a company. That is where fluid management comes into play. There are many ways to fight contamination and fluid loss. Loss of cutting fluid and coolants through chip waste can be solved with a briquetter. A briquetter is a machine that compresses your chips and turnings into a briquette squeezing out ninety percent of your expensive
