Worth it for contractors drilling into concrete, masonry, and granite who need bits that last longer than a Montana winter. The up to 4X longer life compared to standard masonry bits saves money on replacements, and the 1/4-inch hex shank works in impact drivers — not just hammer drills. At 4.4 stars average rating with users praising durability and clean holes, SPEEDemon delivers what Diablo promises.
Skip it if you’re just hanging pictures in drywall. These bits are overkill for basic homeowner tasks, and the higher cost compared to standard bits doesn’t make sense for occasional use.
The Carbide That Actually Lasts
Impact-resistant carbide with a specific brazing and hardening process gives these bits up to 4X longer life than standard masonry bits. That’s not marketing fluff — the optimized u-flute design removes dust quickly to keep the tip cooler, which is what keeps carbide from burning up when you’re drilling post after post for a deck project.
The real difference shows up in tough materials. SPEEDemon bits are one of the fastest drilling solutions for granite and concrete — materials that eat standard bits for breakfast. When you’re setting anchor bolts in a Montana foundation that’s been curing all winter, speed matters as much as durability.

Why the Hex Shank Changes Everything
The 1/4-inch hex shank (Impact Strong™) provides stability and durability in impact drivers and hammer drills. This hex design is superior to standard round shanks for impact usage — no more bits spinning in the chuck when you hit rebar.
The multi-ground Grip Point Tip PLUS™ provides aggressive starts and prevents walking on curved surfaces. Ever tried drilling into river rock for a retaining wall? Standard bits skate across the surface like they’re ice fishing. The Grip Point Tip enables accurate starting without pre-drilling on hard/curved surfaces.
The universal 1/4-inch hex shank fits both impact drivers and standard drill chucks. One bit set works in your hammer drill for heavy foundation work and your impact driver for lighter masonry tasks. That versatility matters when you’re 30 miles from the nearest hardware store.
Real Materials, Real Performance
These bits handle concrete, masonry, stone, granite, brick, block, and marble. Common contractor use cases include drilling into concrete, masonry, and stone in construction, renovation, and repair projects.
The 5-pack includes the sizes that matter: 5/32 in., 3/16 in., 1/4 in., 5/16 in., and 3/8 in. That covers everything from tapcons to wedge anchors. Professional reviews note these sizes handle the range from 5/32” to 3/8”, each 4 inches long.
The optimized flute design helps remove dust efficiently and keeps the bit cooler. Cooler bits last longer. It’s that simple. When you’re drilling dozens of holes for a deck ledger board, heat buildup kills bits faster than anything else.
The Bottom Line for Montana Builders
SPEEDemon bits solve real jobsite problems. The 4X longer life means fewer trips to the store. The hex shank means your impact driver becomes a light-duty hammer drill. The Grip Point tip means accurate holes without pilot drilling.
Sure, they cost more than the bargain bin bits. But when you’re billing by the hour, being one of the fastest drilling solutions for granite and concrete pays for itself on the first foundation job. Professional contractors appreciate the longevity and efficiency in challenging drilling tasks.
For Montana’s freeze-thaw concrete that gets harder every winter, these bits earn their keep. Just don’t waste them on interior work where standard bits do fine.
Frequently Asked Questions
Q: Can I use SPEEDemon bits in a regular drill without hammer function?
The bits are compatible with hammer drills, impact drivers, and drill/drivers. While they’ll work in a standard drill, you won’t get the full performance benefit. These bits are built for impact strength — using them without hammer action is like driving a diesel truck to get groceries.
Q: What’s the actual warranty on these bits?
Diablo accessories typically include a limited warranty; some retailer listings mention a 1-year warranty or 30-day returns. The warranty details vary by retailer, so check with your specific supplier. Most contractors care more about the 4X longer life than warranty paperwork.
Q: Are these bits worth it for occasional homeowner use?
The higher cost compared to standard bits makes these a tough sell for hanging one shelf. But if you’re building a deck, installing a fence, or doing any project with multiple concrete anchors, the up to 4X longer life starts making sense. Buy once, drill right.
Q: What size do I need for standard Tapcon screws?
The 5-pack covers common Tapcon sizes. 3/16 in. works for 1/4” Tapcons (most common), while 5/32 in. handles 3/16” Tapcons. Always check your specific fastener requirements — drilling the wrong size hole is an expensive mistake in concrete.
Q: How do these compare to SDS bits for heavy concrete work?
The 1/4 in. hex shank design means these max out around 3/8” diameter holes. For larger holes or continuous concrete drilling, SDS bits in a proper rotary hammer still win. But for anchor holes and lighter masonry work, the Impact Strong™ hex shank lets you use tools you already own.
