"Comes in a really nice case to keep them in good condition. These are extra long at 300mm, which was perfect for drilling through 15 cm concrete post holes into 10cm wooden posts to allow bolts. They went through the wood easy with a cordless drill."
"Used these initially to insert threaded rods into a 10 inch tree trunk to stop further splitting. Went through live wood with more ease than expected. The 13mm bit was ideal for 12mm rods. Have since used for passing cables through beams. Good fast clean cuts. Really nice zip-up case too."
"Bought these because I needed long bits to drill holes for coach bolts.
Only really needed the 10 x 400 one, but was very impressed with how easy drilling a 200mm hole with this was. I'd expected drilling 30-or-so of these to be quite hard work, but these bits drill through pressure treated softwood beams and posts in just a few seconds.
M10 coach bolts pushed through the holes cleanly and easily.
Screw points a nice touch for accurate positioning of holes."
