B G I Forstner Auger Bit Set for Brace Pat. 1886
This is a very rare set of 3 Forstner type auger bits Each is marked on the tapered square end area "B G I CO. FEB.23.86", some marks more clear than others, each also has the size (10, 13, 16/16s) on it, and the two larger has "PATENT PENDING" also stamped on it. This is a fine example of early thin wall casting production, and machine finish production techniques! All are in good to very good, useable condition with No rust, no other damage, all appear sharp and ready to use except the mentioned above.
Please note that these bits are designed to follow a pre-drilled hole since these were designed with no center lead tip or screw.
A very hard to find set of Forstner bits in very nice shape overall!
