User questions & answers

Question:	How easy do these break? Kinda a cheap price for all these bits

Question:	Does it come packaged in wooden or plastic box? Thanks
Answer:	Yes I would buy it again. However, do a little research on your particular model weed whacker to see which thickness is best for that model. Thinner, breaks more often. Thicker, and square versus round, may not fit the right cord makes a big difference.
Question:	Does this come with a case
Answer:	Thank you for contacting Oregon. Yes you can put an .080" line in a head that uses .095" line. If you any further inquiries, please contact Oregon Technical Services Direct at 1-800-223-5168 option #1.

User questions & answers

Question:	What is the difference between this set, set 1882076 sold at Lowes, and set
Answer:	I use them in my 1/4" dewalt impact drill from time to time , especially in tight spots like small 9" or 12" cabinets. No problems so far.
Question:	Is this a two step process compared to something like the snappy quick-change 5-pc set which is an all-one process
Answer:	All 3 WILL provide more than enough countsink for ALL of your drywall screws to sit below the top of surface. Regardless of whether or not drywall screws are designed for use in wood, anyone who says they haven't is lying.
Question:	How do these handle stainless steel? Will they old up or am I better off just buying disposable Harbor freight
Answer:	You will need a 3/8-inch plug cutter.
Question:	Anybody having issues with slipping? I am just wondering why the round shank and not hex or at least no-slip
Answer:	Its made in China.

User questions & answers

Question:	Newbie question, are these compatible with any type of drills? or are they dewalt exclusive
Answer:	there is a difference can be used for metal they are little harder the other is for wood
Question:	Is this countersink bit for metal or wood
Answer:	Yes. - Different type product, it's 2 steps.1) Drill a hole, then 2) you can come back with this and countersink a spot for the screw head.I've got a similar one, but not Irwin, so I won't comment on quality, but the style seems to work fine. I did notice you can make it "wander" a bit, so if you are trying to line up holes, the other style might be a better choice.
Question:	Would one of these work for a #2 screw
Answer:	They are HSS and should do ok, personally I'd prefer using tungsten carbide tools when working with stainless steel.
Question:	As most wood screws have an 82 degree taper, not 90 degree, are these available in 82 degree taper
Answer:	I've had them a while now. Drilled both wood and steel with them and they're still sharp. It's never slipped for me, however I think the issue of slipping is more related to the quality of your drill. So if your drill has a solid chuck it will be just fine.
