BIG DAISHOWA 20 Ways to Save Time in a Machine Shop

Scenario #13:

Do you perform spot drilling and chamfering in two separate operations? Time-saving solution : You don’t always think about single-purpose tooling solutions. Drills are available to perform both spotting and chamfering. The inside of the drill is a spot drill, but there’s also a second chamfer that smooths the edges. This reduces tool changes, saves fussing with tools in the magazine and avoids secondary hand deburring.

Estimated time savings: 2-4 minutes per hole
