Thanks so much for recommending our tools! We work hard to produce precision, quality bits and I'm so happy to hear that our tools have served the 3 of you well. Our tools have been used on sewing machines for a long time because our hollow ground bits fit the full depth and width of slotted screws unlike typical tapered screwdrivers. Also our bits are engineered to bend/break before damaging the screw.
We've been in business since 1936 and have grown to about 15 people. Most of our new customers are referrals from other customers as we do not have a large marketing budget.
Is there anything that you need that we don't currently make?
Thanks again,
Joel - Chapman MFG
