13Pc 1/16"-1/4" x 64ths 6" Inch Long Aircraft Extension Drill Set

Second purchase - like the bits- I had broken three of the small ones - but my fault bending while drilling- Obviously I liked them to order more.

I need long small diameter drill bits infrequently. So far I have not needed them, so I cannot comment on sturdiness or durability at this time. I hope that when I again have a need for long small diameter drill bits that these bits will do the job.

As in porno, an inch difference is huge. It makes or breaks the production. I needed an inch to complete drilling a passage for a ground wire to make contact & ground my metal guitar bridge. This longer bit went through like butter. The material was poplar, a hardwood.

The long drill bits are perfect for drilling holes in tight places. They allow the drill to stay away from the project being drilled. They work good as drill bits should.

Bought these drill bits to put kitchen cabinets together,these are hickory. Three of the drills broke first time using,broke off inside wood, so had to take a next size bigger drill which also broke,3 drills altogether broke. They might be ok for steel but not wood!

Used one bit to drill a 3 inch hole for a 3 inch screw to help repair a loose dinning room wood chair. Worked very well.

Broke the 11/64 right off. The longer ones seem to break easier
