Speedemon makes carbide-tipped masonry drill bits designed to outlast standard bits by up to 4x. Their focus is narrow but clear: drilling holes in concrete, masonry, and stone faster and with less bit replacement.
The brand appears to be part of Diablo’s tool lineup, though the exact relationship isn’t detailed in available documentation. What matters more is what these bits deliver: aggressive starts, cooler operation, and longer life in materials that eat standard drill bits for breakfast.
Carbide Technology and Grip Point Tips
The headline spec is simple: carbide tips that last up to 4X longer than standard masonry bits. That’s not just marketing fluff when you’re drilling into concrete all day. Speedemon uses what they call a high-performance brazing and hardening process for extreme durability and heat resistance.
The Multi-ground Grip Point Tip PLUS™ provides aggressive starts and prevents walking on curved surfaces. Any contractor who’s tried to start a hole on an uneven concrete surface knows the value of a bit that bites immediately instead of skating around.
The optimized U-flute design removes dust quickly to keep the tip cooler. Cooler bits last longer. It’s that simple. Heat kills carbide faster than impact, and concrete dust trapped in flutes turns into an insulating blanket that cooks your bit from the inside out.
| Feature | Specification |
|---|---|
| Tip Material | Carbide-tipped (Red Granite / Red Granite Plus technology) |
| Durability | Up to 4x longer life compared to standard masonry hammer drill bits |
| Tip Design | Multi-ground Grip Point Tip |
| Flute Design | Multi-ground spiral flutes for rapid chip evacuation |
| Shank Options | SDS-Plus, 1/4 in. Hex (Impact Strong™) |
Size Range and Kit Options
The 5-pack covers the common sizes contractors actually use: 5/32”, 3/16”, 1/4”, 5/16”, and 3/8”. All come in 6” overall length. That’s enough reach for most anchor and fastener work without being so long they flex under load.
Individual bits are available in larger sizes. The 1/4” x 10” x 12” model offers 10 inches of usable length for deeper drilling applications. The 1/2” x 4” x 6” bit handles larger diameter holes with 4 inches of working length.
The Impact Strong™ hex shank provides stability and durability in impact drivers and hammer drills. This matters because more contractors are switching to impact-rated accessories as cordless tools get more powerful. The hex shank won’t slip in a three-jaw chuck like round shanks can.
| Size | Working/Usable Length | Overall Length | Shank Type |
|---|---|---|---|
| 5/32” | — | 6” | 1/4” Hex |
| 3/16” | — | 6” | 1/4” Hex |
| 1/4” | 10” | 12” | SDS-Plus |
| 1/4” | — | 6” | 1/4” Hex |
| 5/16” | — | 6” | 1/4” Hex |
| 3/8” | — | 6” | 1/4” Hex |
| 1/2” | 4” | 6” | 1/4” Hex |
Battery Life and Cordless Performance
Speedemon bits are designed to deliver more holes per battery charge. That’s not just convenience on a jobsite — it’s money when you’re 40 miles from the nearest town and your spare batteries are back in the truck.
The optimized U-flute design keeps the bit cooler, which translates directly to less power draw. A hot bit requires more torque to maintain speed, which drains batteries faster. The high-performance brazing and hardening process extends tip life, meaning the cutting edges stay sharp longer and require less force to penetrate.
These bits work in corded/cordless impact drivers and hammer drills. The versatility matters when you’re switching between a corded SDS for heavy drilling and a cordless impact driver for quick anchor holes.
The Bottom Line
Speedemon carbide bits do exactly what contractors need: drill holes in concrete faster and last longer between replacements. The 4x longer life claim translates to fewer trips down the ladder to swap bits and fewer bits to stock on the truck.
Skip these if you’re only drilling wood or soft materials — that’s like buying a diesel pickup to drive to the office. But for contractors punching holes in concrete foundations, masonry walls, or stone surfaces, the carbide investment pays off in time saved and bits not bought.
The materials list includes concrete, masonry (brick and block), stone, marble, granite, red granite, tile, and hard stone. That covers pretty much everything contractors encounter except steel, which requires different bit technology entirely.
Frequently Asked Questions
What’s the difference between SDS-Plus and hex shank Speedemon bits?
SDS-Plus shanks are available on larger bits like the 1/4” x 10” x 12” model, designed for dedicated hammer drills. The 1/4” hex shank (Impact Strong™) works in both impact drivers and hammer drills, offering more tool flexibility but potentially less power transfer in heavy-duty applications.
How much longer do these really last compared to standard masonry bits?
Speedemon claims up to 4x longer life than standard masonry hammer drill bits. Real-world performance depends on the material you’re drilling, technique, and tool power. The carbide tip and improved heat dissipation are the key factors in extended life.
Can these bits be used in impact drivers?
Yes, the hex shank models with Impact Strong™ technology are designed for stability and durability in impact drivers. They’re compatible with both impact drivers and hammer drills. The SDS-Plus models require a hammer drill with the appropriate chuck.
What sizes come in the 5-pack?
The 5-pack includes 5/32”, 3/16”, 1/4”, 5/16”, and 3/8” bits. All are 6” overall length with 1/4” hex shanks.
What materials are these bits designed to drill?
Speedemon bits handle concrete, masonry (brick and block), stone, marble, granite, red granite, tile, and hard stone. They’re specifically engineered for hard, abrasive materials where standard twist bits would fail immediately.
