Ratings & Reviews for IRWIN SPEEDBOR MAX 1/2-in x 6-in Woodboring Tri-flute bit Drill Bit

Great bit, clean holes with handheld drill

This thing worked perfect for putting holes in thick boards with only a handheld drill. Takes a lot of power but the screw guide at the bottom made it really easy to line up the hole perfectly.

Great masonry bit, staying sharp!

Good bit

Pulls itself through wood good. Doesn't like nails but which ones do.

Works well

This bit bores like a dream. The only issue I had was that it clogged if I drilled more than about two inches, so I had to pull it out to clear clear the debris. Might have been because the treated wood was not dry.

Works great for drilling holes in tree stomps very fast. However,if using a powerful drill, you need to back the drill bit out a few times as you drill deep to prevent binding which will snap the shank off the bit.

1 bit to drill them all

I use 1/2” more than anything in my line of work. This bit beats all competitors

drill bit

Cut thru joist like butter, excellent product

Very powerful

This did the trick although I have only used it a few times at this point. Probably best with a larger, more powerful drill. I have a smaller drill and it turned ME around.

IRWIN 5/8-in Woodboring Tri-Flute Drill Bit

I need to drill a hole through double headers in a tight spot. My spade bits were not doing the job (guessing I hit a knot), The Tri-Flute bit went right through with no problems,

Worked great. I used this for drilling holes in my lumber and using rebar to secure.

Tri-Flute Drill Bit

Very few 5/8' wood drill bits available but had to settle for a tri-flute bit. Would preferred a 3/8" shank instead 1/4" shank. Too much tear-out. Preferred a wood twist drill bit but the store did not have any in stock.

Positive

Always a positive experience when buying from Lowe’s. The drill bit i purchased was exactly what i needed for my home project. Always a satisfied customer.

Makes a clean exit hole

This drill bit works well, at least it has through a job requiring four or five holes. It makes a cleaner exit hole than a spade bit, which is ciritical depending on the job. I don’t know how well it will hold up, but so far no complaints.
