Irwin is introducing new multi-material drill bits that can be used on wood, metal, plastic, laminates, brick, block, tile, and marble. As with Bosch’s multi-construction bits and Dewalt’s multi-material bits, Irwin’s new bits can also work with multi-material layers.
These new bits have unique diamond-ground carbide tips with super-sharp cutting edges for improved accuracy and hole-boring quality.

Jon Schlosser, Director of Marketing for Irwin Tools, said the following about why Irwin developed these new drill bits:
We literally talk to hundreds of professional tradesmen each year, simply to learn what’s most important to them on the jobsite. They repeatedly express frustration with having to carry around multiple types of drill bits, and switch out bits depending on a particular material they need to drill into at any given time. It’s time consuming and discouraging.
With IRWIN’s new multi-material bits, tradesmen can drill through all sorts of materials with a single bit… These bits will drill right through every layer of building materials.
You can use these bits with any standard 3/8″ and 1/2″ drill. Standard jobber bits will be available in 3-5″ lengths and extended-length bits will be 16″ long. Sizes will range form 1/8″ to 1/2″.

The 10-piece set (SKU 1792772) comes with 1/8″, 5/32″, 3/16″, 7/32″, 1/4″, 5/16″, 9/32″, 3/8″, 7/16″, and 1/2″ bit sizes for about $40. It looks like this is the complete selection of multi-construction bits Irwin offers.

Are these basically the same as the Bosch Multi Construction bits?
Stuart
In theory, yes. In practice, there could be a difference since Irwin had plenty of time to analyze and counter Bosch’s design.

I think I recall that Irwin had marketed multi-matrial drill bits in the past made by a company called Juran (not sure of my spelling) made in Denmark

I hope they make these in larger sizes. I sometimes do work requiring me to drill through wood or heavy sheet metal, then into a synthetic post (made from recycled materials, including tires, where they reuse the rubber for running tracks, and use the steel belts as ‘rebar’ in the posts). They are very hard on standard drill bits, a masonry bit is the bit of choice, but they do not drill through steel worth a hoot. These in 5/8 and 3/4, in a length long enough to go through both 2X lumber, and a 6″ post, might sell.

They appear to be hammer drill bits with a longer flute. Have you tried regular hammer drill bits for your application?
