Drill Drives Tool Life, Cycle Time Improvements
This shop upgraded to through-spindle coolant as part of a lean manufacturing initiative but soon experienced tool life issues in drilling applications. With the Performax drill from Seco Tools, the shop not only addressed this problem, but also reduced costs and cycle time.

Drill Helps Shop Balance Cycle Time, Part Quality
At Mill Equip Products, getting components out the door quickly is extremely important. A difficult drilling operation had the shop considering a $5,000 option for its milling machine to reduce cycle time until it found a simpler, less costly solution—the R458 MP-X drill from Dormer Precision. The drill’s geometry and long tool life enabled the shop to reduce production time on the job by more than two weeks.

Adjustable Drill Drives Inventory Cost Savings
During a difficult application, the inserts on this shop’s standard IC drill would sporadically fail, causing the entire tool to break down. This required the shop to stock a large inventory of costly replacements in various sizes to fit different-sized holes. Allied Machine and Engineering’s Revolution drill allows the shop to adjust tool diameter and cut holes of different sizes with a single tool, while replaceable insert cartridges on the front end keep insert failure from wrecking the tool itself.

Hole Making: Combination Tools
This video demonstrates hole making. Hole making often involves sequential operations such as drill-then-tap. Combination tools that perform these operations simultaneously can eliminate tool changes, saving cycle time. Many combination tools call for helical interpolation. The video shows the same series of hole
