The Diablo DHS14SGP 14-Piece General Purpose Bi-Metal Hole Saw Set is a multi-size hole saw kit for drilling clean, repeatable holes in wood, plastic, aluminum, metal, and stainless steel. This is a bi-metal hole saw set designed for general-purpose hole cutting across common jobsite materials. Model Number: DHS14SGP. If you need one case that covers a wide spread of hole sizes without piecing a kit together one cup at a time, this set is built for that job.

The big performance advantage here is the 60 mm, or 2-3/8 inch, cutting depth. Diablo states that gives you 40% deeper holes in one pass, which matters when you are working through thicker stock and do not want to flip material, re-start the cut, or fight a half-finished plug. On the job, that translates into cleaner workflow and less wasted time when you are roughing in pipe, conduit, locksets, or pass-throughs.

Another standout is the Snap-Lock Plus mandrel system. Hole saw sets live or die by how easy they are to swap, especially when you bounce between sizes through the day. Diablo built this setup for quick and easy cup changes, and the one-size mandrel fits all Diablo hole saws from 5/8 inch to 6 inch diameter. That is useful if this set is your starting point and you plan to add larger or specialty cups later without changing over to a different mounting system.

The variable tooth design is there for a reason, not just for the spec sheet. Faster cuts with less vibration usually mean better control, smoother entry, and less chatter once the teeth start biting, especially in mixed material work where you are moving from wood to sheet metal or plastic. For electricians, plumbers, HVAC installers, remodelers, and general contractors, that kind of predictable cutting behavior matters more than flashy packaging.

Diablo also built in tool-free plug ejection for faster material removal. Anyone who has spent time digging a scorched wood slug out of a hole saw knows why that matters. Faster plug removal keeps you moving, especially during repetitive drilling work where every stop adds up. It is one of those features that sounds small until you use it all day.

This set includes ten bi-metal hole saw cups, one mandrel, one pilot bit, and two adaptor nuts in 1/2 inch and 5/8 inch sizes. The included hole saw diameters cover a useful range for everyday drilling and fastening prep, from smaller utility holes up to larger openings for hardware and rough-ins. Because it comes in a dedicated case, it is easier to keep the full set together instead of losing cups and adapters at the bottom of a toolbox.

Who is this set for? It makes the most sense for tradespeople and serious DIY users who need a versatile hole saw set for wood, plastic, and light metal cutting without stepping into a more specialized carbide setup. If your work includes general construction, remodeling, service calls, or shop fabrication, this kit covers a lot of common sizes and keeps size changes quick.

If you mostly drill occasional holes in one material and one size, buying a single cup might be smarter. But if you need a dependable general-purpose kit that handles a range of materials and keeps the mounting process simple, the Diablo DHS14SGP is the kind of set that earns a spot in the van instead of sitting on a shelf.

Why the Diablo DHS14SGP 14-Piece General Purpose Bi-Metal Hole Saw Set Makes Sense
