User questions & answers

Question:	Does it work with dremel
Answer:	Check your phone for messages or emails and could be coming in the next shipment or, due to human error was delivered somewhere else.
Question:	Where is the rest of my order
Answer:	Yes
Question:	Will they work on aluminium
Answer:	Not sure of the grit or grade of coatings but all three are the same. When I purchased them I thought they were different. No remorse though as I imagine some will break or wear out or get lost. Still pleased with my purchase.
Question:	What grit are they? Is each set the same grit or three different grit sets
Answer:	These tools are made for 15000 RPM and to a Maximum of 35000 RPM range. Your hand drill has a maximum of 1200 to 3500 RPM. They will fit but the user will struggle to maintain control of either the drill or the material being cut. Note: it may be possible to cut and remove material from balsa wood, or styrofoam withe these bits, but I wouldn't recommend it. If your looking for a tool that has nice cutting ability for these bits try using JET JAT-401 Pneumatic R6 Die Grinder, 1/4" https://www.amazon.com/dp/B010VAC95W/ref=cm_sw_r_cp_apa_i_tkkaEbMRS290F powered by an air compressor, or Populo High Performance Rotary Tool Kit with 107 Accessories, 3 Attachments, Variable Speed, Flex Shaft and Universal Collet for Abrasive, Polish, Cutting, Engraving, Drilling and Crafting DIY Project https://www.amazon.com/dp/B07HRHC9X7/ref=cm_sw_r_cp_apa_i_2mkaEbHW2S958

User questions & answers

Question:	Does this fit Makita hammer drill
Answer:	No. they require an SDS+ chuck which the PS41B does not have. For light duty work, try http://www.amazon.com/Greenlee-MAS-SET-9-Quick-Change-Masonry/dp/B005NN93G6/ref=sr_1_10?ie=UTF8&qid=1408574063&sr=8-10&keywords=1%2F4%22+hex+masonry+bits.

Answer:	OH gotta love Amazon... wow. No apples LOL
Question:	will these bits fit a bosch PS41B impact driver
Answer:	Depends what size hole you want to drill. These are extremely small diameter and easily broken. I would suggest you don't try to drill holes this small unless you absolutely have to. And if you do, use extreme care.
Question:	Does this include apples? I'm confused by the product description
Answer:	I do not know what size collet the WEN tool has but I used these in a Dremel Collet, with my Dremel. So if WEN and Dremel use the same size collet they should work. If not ???

Question:	Will this work with a craftsman hammer drill

User questions & answers

Question:	Anyone know if these will fit a Dremel Moto-tool
Answer:	I don't know about shotgun barrels. I'm using them on knife blades. Should be about the same. I just take my time and don't rush.
Question:	are these 3sets of the same bits
Answer:	Although I can not give you a definative answer, my guess would be yes, but need to keep water on the drilling area. Go slow. I engrave on glass as a hobby and never encountered any problems going deep , BUT...glass and porcelain are different of course. GO SLOW...VERY SLOW, WITH VERY LITTLE PRESSURE ON THE BIT. USE PLENTY OF WATER. HOPE THIS HELPS YOU. GOOD LUCK.
Question:	How effective are these on shotgun barrel
Answer:	Hi! The HC2069 is compatible with tools that accept SDS-plus bits. We recommend getting in touch with the manufacturer of Bauer to confirm the compatibility. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.
