Visit retailer opens the shop. Affiliate disclosure.
This page compares live feed prices for Irwin IRWIN® Blue Groove 4X Long Flat Bit 16 x 400mm 10502836 by Irwin in Flat Drill Bits. 3 shops currently list it in the selected country. Visit retailer is an affiliate hop. You finish the order on the shop’s site.
Check the photo matches the name. If the image is missing, treat the row as incomplete. The lowest price is the lowest feed number we have — not a promise about postage, stock or the exact variant on the shop page.
We do not write retailer descriptions from scratch. Feed text is cleaned, not turned into a review. For how we match shops and when to skip a click, read how to read a listing and how we compare prices.
No reviews yet. If you bought this, write what you used it for — that helps the next shopper more than the feed description.
