These are high-carbon steel bits with standard brad points (BP).
They do not enter as cleanly, clear chips as well, or stay sharp as long as our HSS bits. These are suitable for the hobbyist, or where occasional use does not justify the higher cost of a HSS bit.
Available in Imperial and metric sizes. Bits have shank sizes of 1/4" for 1/4" to 1/2" bits, 3/8" for 5/8" to 1", 10mm for 10mm to 20mm, and shanked to size for 1/8", 3/16", and all other metric bits.
Length increases from 2-1/2" on the smallest bit to 8" on the largest.
The 7.5mm Brad-Point is no longer available.
