User questions & answers

Question:	I just bought this kit and one of the bits came with a totally rounded shank but the others have a flat side on it, is it normal
Answer:	These are High Speed Steel Cobalt Coating.
Question:	Are these HS titanium coated ? Thank you
Answer:	They sell them at sears http://www.sears.com/neiko-5-piece-step-drill-bit-set/p-SPM5125841201Pthey say Reg Price: $77.99 Savings: $37.00 price $40.99 made in Imported (Taiwan)
Question:	What is the country of origin of this set of step up bits
Answer:	Sadly to say that it does not hold up to stainless steel. I am an Exterior Electrician and ordered a bunch of these for my guys to use out in the field. It did not work on our Exterior panels nor on our Transformers the first, second or third time. The bits gave out and dulled as soon as they started drilling. We ended up purchasing high end step-bits we've ordered before and they worked well. I did a trial with these bits and ended up short on the winning end.
Question:	Do these hold up to heavy use on stainless steel
Answer:	Absolutely, it can. However, if I were you I would attempt that job with a high tempered heat treated drill bit and a dab of cutting oil to preserve the bit. Good drilling to you and be safe please.

User questions & answers

Question:	How thick of mild steel can these stepper bits drill through
Answer:	Depending on the bit you are talking about, the step down is different. The skinny one has step downs measured in 1/16 steps and so does one other. The fat one steps down in 1/8 steps. If you look carefully at the pictures you may be able to read the increments or in some of the descriptions the steps are indicated. If you purchase the three bit set you will be able to drill any sized hole you should ever need. I used these on aluminum and other non ferrous materials that are fairly thin. If you are drilling in wood or getting ready to do a wood working project then you may want to reconsider and purchase individual drill bits.
Question:	What is the depth of each increment
Answer:	I just drill 4 holes in 1/4 thick wall on 4 inch x 4 inch steel tubing going up to 3/4 diameter ...cut like butter. These are awesome.
Question:	What are these things for? Maybe I can use them
Answer:	Hi Randy,The 3/16"-1/2"(six step drill) and the 1/8"-1/2"(thirteen step drill) both have 1/4" shank. The 1/4"-3/4"(nine step drill) has a 3/8" shank. Hope this will help you?
Question:	What size is the shank
Answer:	Please contact the seller directly for warranty information for this product. You may also be able to find warranty information on the manufacturer’s website.

User questions & answers

Question:	How good is the quality
Answer:	This is a set of 5 drill bits. You can use either 3/8 or 1/2 drill with the drill bits included.
Question:	Is this for a 3/8 drill or
Answer:	You don't "need" any of these bits. Both, my...another family member and I purchased these as the touting of cobalt, titanium, and High Speed Steel bits made us both believe they were a steal of a steel deal. Boy we couldn't have been more wrong! Destroyed 1st use at slow speed off the speed chart and using tapping fluid to lubricate. These are absolute garbage. AGAIN THESE ARE ABSOLUTE GARBAGE BITS. I've got a free pocket knife from a gas station that drills better. Shavings from the first time we used these bits were put in the MassSpec at his showed NO cobalt at all present. For those that don't know a mass spectrometer gives you a breakdown of the molecules and elements present in a sample. Upon my complaining to the seller, I was told well.... "They're only cobalt colored and aren't intended for use on steel or hard metal alloys." You buy a cobalt %containing bits to handle the higher frictional heats encounters when cutting/drilling tougher steel alloys, stainless, or even just wanting your High Speed Steel bits to last longer. It's so your bit doesn't take damage and be destroyed or worse yet damage the piece you're drilling (especially when you're using tapping fluid too to lubricate the cutting edges reducing that friction and subsequent damaging heat) and M42 is the highest grade of cobalt bits I have & that I know of / have used. You buy titanium bits from M7 (high molybdenum for toughness) to M35 (HSS with a 5% titanium component) or the king of titanium bits and heat dissipation (HSS with 8% titanium) so your bits won't be damaged to the point they're unable to be used again. These high end bits you pay for ones made right. There are proper recipies the boundaries mix up molten of all the components from the iron and nickel of base steel, to adding molybdenum for toughness, cobalt for thermal resilience, titanium coatings to reduce friction, and many many more components in a bakery for steel. These bits are beyond poorly made and are NOT good moreless decent bits. So I'll reiterate fro my own and others experience, THESE ARE JUNK AND YOU DONT "NEED" THEM.....well unless you need to drill holes in pure Gallium at ambient temperatures above 30°C. And just a FYI I have 1/8" M42 aircraft legnth bits that'll drill through a 10" hardened steel block and a 1.0" M42 bit that could just about drill aluminum foil without tearing it. Size has nothing to do with quality. Small bits for small sheets and big bits for big sheets is a cop out answer to make the customer think they're the problem in how they're using the bits. The bits are crap and the Seller sends different answers to different people. They're garbage bits from cheap garbage metal (I hesitate to even call them true steel) see less
Question:	Are these bits titanium or cobalt? The product description shows both titanium & cobalt
Answer:	You don't "need" any of these bits.

Answer:	It will definitely cut aluminum...its I deal for porting a cylinder head...

User questions & answers

Question:	Will this reamer allow me to enlarge my circular saw's 10mm arbor to
Answer:	It might work. I used mine to open up 9/16" holes to 3/4" in a maple work bench top.A few things to consider; material (there are a great many grades of stainless out there and some a very hard to machine), material thickness (I'd be slow to try it with anything 1/16" and up. Even something approaching 1/16" may be ambitious.), available torque (most portable drills would not be up to the task - you could smoke the motor). You might want to consider either a manual-type tapered reamer or a circular file. On the face of it, you are only removing 0.010" all around. I hope that was helpful.
Question:	I have a 3/4" hole I want to open up to .77" the material is sheet Stainless Steel. Would this work
Answer:	I use a 7/32 before I use the 3/8 Triumph drill
Question:	Can anyone tell me the diameter of the 3/8" reamer at the tip? I'm looking for a reamer to enlarge a 1/8" hole, will the 3/8" bit fit into it
Answer:	The angle of the dangle is inversely proporhonal to the heat of the meat, Provided that the maxis of the axis, and the gravity of the cavity, remain constant
Question:	I ordered the 1/2". Does anyone know what the angle of the dangle is
Answer:	No case, but for the price they are okay. I found the tips of the bits can break easily though if you're not careful.
