Review on CaRoller 29-Piece Cobalt Plastic Set by Ken Reed

Revainrating 5 out of 5

M35 5% Cobalt Set of 29 SAE Drill Bits with 1/16 "-1/2 " split points on 64 - great value!

I enjoy doing woodwork and housework, as well as most of my own work as an auto mechanic. Fixing my own stuff is a joy when I have the right tools on hand, especially quality drill bits. This is a set of 29 SAE M35 HSS 5% Cobalt (HSS-Co) drill bits in a plastic cup holder. This complete set has split points, which I liked seeing as it makes it easier to start the hole without "walking". Included Sizes: 1/16", 5/64", 3/32", 7/64", 1/8", 9/64", 5/32", 11/64" , 3/16", 13/64", 7/32", 15/64", 1/4", 17/64", 9/32", 19/64", 5 /16", 21/64", 11/32", 23 /64", 3/8", 25/64", 13/32", 27/64", 7/16", 29/64", 15/32", 31/64" and 1/2" plus in a pinch you can approach metric hole sizes. Shanks have stamped dimensions - flat ground shanks on large bits (nobody has triangular bits) .There is no triangular shank which is REQUIRED to keep the bit from spinning in the chuck a Jacobs wrench no halves, standard I take 5 as otherwise it's a good set they are sharp and will bore with use easily through stainless steel with a good quality cutting oil such as Evo Dyne Cutting Fluid When SS drilling, use a lower RPM (550) and start with a small starting hole before progressing to a large size for best results I have the cracked plastic Bit bowl with fiber cl ebeband repaired, no big deal. I recommend this CaRoller brand 29 piece drill bit set, M35 cobalt steel (1/16" - 1/2" x 64), 135 degree round shank point. without OUT Three Flats. I hope you found the information and my review helpful.

Pros
