Dangerous times ahead!

... for my wallet!

It's time for the annual Tasmanian "AGFEST" Field Day/Agricultural Show. This means discovering things that 'I never knew that I needed'. I've gone every year for the past 4 years and (bar the first year) always reckon that there couldn't possibly be anything more that I needed.

WRONG. I even tried bringing along a 'wallet minder' Mate on a couple of occasions but he mostly said, "Oooh, you need that!" (Then he promptly borrowed 'it' later on.)

This year's "Whiz-bang" object is a set of drill bits that, frankly, sound too good to be true: ARTU | Drill Bits, Hole Saws & Saw Blades

Are there any recommendations of objects/tools/etc... that you've found at your shows that you "never knew that you needed it"? Were they a dud or worked better than expected?

Wagtail I am using a set of drill bits my Dad said he got at Ag. class in his 8th year of school. also final year of his education. so around 1920 He had enough schooling to be able to make a living.
Could use the carpenter square like a slide rule and figure pitch of building rafters
with a hand driven drill press made a tractor. repaired farm machinery and the one set of drill bits just kept cutting with small amount of sharpening cuts well today.
I have bought the Harbor Freight drills and had them unwind or break just as the hole is finished.

so if the bits you show work (they look like concrete bits to me.) would be interested if could be purchased in the u.s.

G'day Ken. Here's a different website that shows & describes these bits: 7 Piece ARTU Drill Bit Set - Metric - Newstyle Direct

Mind you, it's from the manufacturer. It looks like it's 'all in the tip' with no cutting edge on the shaft. They also come in Imperial.

The 'post #1' website is a US site.

Thanks for posting. Interesting and capable looking drill bits and Amazon carries them.

I have not tried this brand, but use them in my stone carving. The files work real well on stone and clean up with a with brush. Jig saw blades do work but dull after maybe 5-6 ft of cutting 3/4 in thick limestone. But to be fair, that's a lot of cutting.

The glass drilling bits are amazing on stone. I have a set from 1/8 to 1 inch. The saw-all blade works well in a holder

Please be advised that ARTU Multi-Purpose Drill Bits are not recommended to be used on mild steel, i.e., angle iron, galvanized pipe, copper, aluminum, brass, stainless steel, etc. Instead use ARTU’s HSS or Cobalt Drill Bits.

Those bits are masonry bits. ONLY.

I used to attend the Melbourne Working With Wood Show and there was a bloke selling drill bits in a set, he demonstrated by drilling through a file and had obviously aroused someones suspicions as they barged in with a drill and bit and tried it and drilled a hole while he was trying to get him off his display.
It appears the files were heated (de-tempered?) and anything would bore through them.
He was easily identified with his loose fitting dentures and constant opening and closing of his mouth to keep them in place, I hope this is not him.

Very good point K0ua and something that I missed amongst all of the "look at all it can do" advertising: "especially suited to the heaviest duty applications in masonry, brick, ceramics, cast stone and natural stone."

And, yeah bunyip, you really have to be aware/cautious regarding slick spruiking. "Buy NOW! Show SPECIAL! We're practically giving them away!!!" :laughing:

I borrowed someone's superduper bit, after he talked up how indestructable and everlasting they were, I promptly broke it......

I wonder if the ARTU's would top these - Amazon.com: Rotary Percussion Masonry Drill Bit: Home Improvement

They have always given me very good service.
