UNTIL THE MORE GENERAL USE OF TWIST BITS THE CENTRE BIT WAS THE MOST COMMON OF WOODWORKING BITS. IN USE THE NICKER OR SHARP SPUR-CUTTER DESCRIBES A CIRCLE AROUND THE CENTRE SPIKE; THE CUTTER PARES AWAY THE SURFACE INSIDE THE CIRCLE. THIS BIT HAS CUT-OUT SECTION IN TANG, INDICATING ITS USE IN SPRING-LATCH BRACE. THESE BITS COULD ONLY BE USED IN A PARTICULAR BRACE, AS SIZE & POSITION OF CUT DIFFERED. C.1868 SQUARE TANG SPOFFORD & BARBER BRACES INTRODUCED, ELIMINATING THIS PROBLEM. (SALAMAN, PP.75-77)
