Description of π§ A26S CO SET Machine Degrees by Drill America
Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. 26 piece drill bit set comes in a metal case.
The A26S CO SET Machine Degrees I recently purchased is a fantastic addition to my collection of cutting tools. Through trial and error, I found that these industrial-grade drill bits are extremely durable and long-lasting, able to withstand my toughest projects. The variety of sizes included in the set is impressive and has helped me tackle all of my industrial and scientific drilling needs. The only downside I found is that the set is a bit pricey, but the quality of the product justifies the
Pros
High-quality material ensures durability and long-lasting use.
Cons
Requires a certain level of expertise to operate effectively.
It's refreshing to buy something from Revain that is made in the USA. Every bit is straight, every bit is sharp, and most bits will cut a hole within 0.002 inch of the marked size. Bits 1/4 inch. For 99.9% of you it's perfect, but for me it's good enough for a government job. I highly recommend these beats. Even if you have room for full sized bits, get some as very few ever need the extra length of full sized bits and shorter bits are much more difficult to bend.
Pros
Counterclockwise (right hand cut) movement Spiral grooving tools remove chips up and out to reduce clogging
Like the others listed, I received 5 incompatible bits in my set. However, they were all marked "NAS 907 (drill size) CO". A quick search reveals this to be a precision twist drill, made in the USA from the same 907 alloy as advertised. Tip angle, tip spacing and length are as expected. The only difference besides the markings is the smooth black coating on the bands of these bits for improved chip evacuation; only present on precision twist bits. This confirms my suspicion that Drill Americaβ¦
