What Are the Differences Between Single and Multiple Point Cutting Tools?
Cutting tools are used to slowly remove excess materials through shearing. Cutting tools come in various features and shapes, depending on the work it’s intended to do. However, all quality cutting tools have a portion that’s wedge-shaped that has a sharp cutting edge.
Cutting tools can either have one or more cutting edges. So knowing the difference between these tools can help you choose the right one for your current task. Also, using the correct tool for the job will let you finish faster and with accurate results.
Categories of Cutting Tools
Quality cutting tools fall under three categories: single point, double point, and multi-point. As their names suggest, a single-point cutting tool has one cutting edge. A double-point cutting tool has two cutting edges. Lastly, a multi-point cutting tool has more than two cutting edges.
There is only one example of a double-point cutter, and that’s the metal cutting drill. As a result, double-point cutters are sometimes merged with multi-point cutters. So in some instances, some people may differentiate cutting tools as single and multi-point cutters only. As is the case with dealers who have a wide range of cutting tools.
Differences Between Quality Cutting Tools
Single-Point Cutting Tools
They have only one main cutting edge.
There is typically a high chip load per tooth.
During machining, there’s only one main cutting edge that is constantly in contact with the workpiece.
There is a high rate of heat generation due to the single cutting edge that’s always in contact with the workpiece. As a result, the tool’s temperature rises quickly, too.
In case that the cutting edge breaks, the whole task may have to be postponed until the cutting edge is replaced.
SIngle-point cutting tools are easier to design and manufacture.
Low feed rate and depth of cut are typically used when machining using single-point cutting tools. This results in a low material removal rate (MRR) and productivity.
Multi-Point Cutting Tools
Multi-point cutting tools contain from two to a hundred cutting edges.
In a single pass, more than one cutting edges are in contact simultaneously with the workpiece.
Chip load per tooth is reduced.
Since the multiple cutting edges are in a cycle of engaging and disengaging with the material, heat dissipates faster. As a result, the cutting tool’s temperature doesn’t rise quickly.
In instances where one of the cutting edges break, the task can still be continued. That’s because the other cutting edges can continue the cutting without any hitches.
Designing and manufacturing multi-point cutting tools can be challenging
A higher feed rate can be used when machining using multi-point cutting tools. This results in an increased MRR and productivity.
Knowing the difference between cutting tools can help you decide on which works best with your task. Therefore, you get to finish your work faster and more accurately. Also, for better results, make sure you only get quality cutting tools, like the ones from Suncoast Precision Tools. That way, you’re confident that your tools are made of top-grade materials that will last for a long time.
