HSS Foret Speed Chart
The table below shows recommended tr/min for standard HSS (Acier rapide) forets. Values are calculated using the formula tr/min = (Surface Speed × 1000) / (π × Diameter) with standard vitesse de coupes: Mild Steel 25 m/min, Acier inoxydable 15 m/min, Aluminum 75 m/min, Fonte 20 m/min.
| Bit Diameter | Mild Steel (tr/min) | Acier inoxydable (tr/min) | Aluminum (tr/min) | Fonte (tr/min) |
|---|---|---|---|---|
| 1 mm | 7,960 | 4,775 | 23,875 | 6,365 |
| 2 mm | 3,980 | 2,390 | 11,940 | 3,185 |
| 3 mm | 2,650 | 1,590 | 7,960 | 2,120 |
| 4 mm | 1,990 | 1,195 | 5,970 | 1,590 |

| 25 mm | 320 | 190 | 955 | 255 |
Tip: Use cutting oil or coolant for all métal percage. Reduce tr/min by 20–30% for deep holes (depth > 3× diameter).
Pointe en carbureped Foret Speed Chart
Carbide-tipped and solid carbide forets can operate at significantly higher surface speeds than HSS. Typical vitesse de coupes: Mild Steel 60 m/min, Acier inoxydable 35 m/min, Aluminum 150 m/min, Fonte 50 m/min.
| Bit Diameter | Mild Steel (tr/min) | Acier inoxydable (tr/min) | Aluminum (tr/min) | Fonte (tr/min) |
|---|---|---|---|---|
| 1 mm | 19,100 | 11,140 | 47,750 | 15,915 |
| 2 mm | 9,550 | 5,570 | 23,875 | 7,960 |
| 3 mm | 6,365 | 3,715 | 15,915 | 5,305 |
| 4 mm | 4,775 | 2,785 | 11,940 | 3,980 |
| 5 mm | 3,820 | 2,230 | 9,550 | 3,185 |
| 6 mm | 3,185 | 1,855 | 7,960 | 2,650 |
| 8 mm | 2,390 | 1,390 | 5,970 | 1,990 |
| 10 mm | 1,910 | 1,115 | 4,775 | 1,590 |
| 12 mm | 1,590 | 930 | 3,980 | 1,325 |
| 16 mm | 1,195 | 695 | 2,985 | 995 |
| 20 mm | 955 | 555 | 2,390 | 795 |
| 25 mm | 765 | 445 | 1,910 | 635 |
Remarque: Solid carbide bits achieve higher speeds than carbide-tipped bits. Use through-tool coolant when available. Rigid machine setup is essential for carbide tooling.
Maçonnerie & Béton Foret Speed Chart
Maçonnerie bits (SDS-Plus and SDS-Max) are used with perforateurs. The tr/min is lower than métal percage because the hammer mechanism provides the primary cutting force. These values represent typical perforateur settings.
| Bit Diameter | Emmanchement Type | Béton (tr/min) | Brick (tr/min) | Block (tr/min) |
|---|---|---|---|---|
| 5 mm | SDS-Plus | 1,100 | 1,400 | 1,500 |
| 6 mm | SDS-Plus | 1,000 | 1,300 | 1,400 |
| 8 mm | SDS-Plus | 900 | 1,100 | 1,200 |
| 10 mm | SDS-Plus | 800 | 1,000 | 1,100 |
| 12 mm | SDS-Plus | 700 | 900 | 1,000 |
| 14 mm | SDS-Plus | 600 | 800 | 900 |
| 16 mm | SDS-Plus | 550 | 700 | 800 |
| 20 mm | SDS-Plus | 450 | 600 | 700 |
| 22 mm | SDS-Max | 400 | 500 | 600 |
| 25 mm | SDS-Max | 350 | 450 | 550 |
| 28 mm | SDS-Max | 300 | 400 | 500 |
| 32 mm | SDS-Max | 250 | 350 | 450 |
Important: Always use hammer mode (rotary + impact) for béton. Brick and block can sometimes be drilled in rotation-only mode with light pressure. Never force the bit — let the hammer do the work.
Wood Foret Speed Chart
Wood percage generally allows higher tr/mins than métal. However, larger bits — especially grandes meches bois and scies cloches — must run slower to prevent burning and maintain control.
| Bit Diameter | Bit Type | Bois tendre (tr/min) | Bois dur (tr/min) |
|---|---|---|---|
| 3 mm | Twist / Brad Point | 3,500 | 2,500 |
| 5 mm | Twist / Brad Point | 3,000 | 2,000 |
| 8 mm | Twist / Brad Point | 2,500 | 1,500 |
| 10 mm | Twist / Brad Point | 2,000 | 1,200 |
| 12 mm | Brad Point / Spade | 1,800 | 1,000 |
| 16 mm | Large wood bit | 1,500 | 800 |
| 20 mm | Large wood bit | 1,200 | 700 |
| 25 mm | Large wood bit | 1,000 | 600 |
| 30 mm | Large wood bit / Scie cloche | 800 | 500 |
| 35 mm | Large wood bit / Scie cloche | 700 | 400 |
| 40 mm | Scie cloche | 600 | 350 |
| 50 mm | Scie cloche | 450 | 250 |
Tip: Back off the pressure periodically to clear chips, especially with grandes meches bois. Use a sacrificial board underneath to prevent blowout.
How to Calculate Drill Speed
The universal formula for calculating foret tr/min is:
tr/min = (Vitesse de coupe × 1000) / (π × Diameter)
Where:
- Vitesse de coupe = surface speed in meters per minute (m/min)
- Diameter = foret diameter in millimeters (mm)
- π = 3.14159
Common Vitesse de coupes by Material (HSS Bits)
| Material | Vitesse de coupe (m/min) |
|---|---|
| Mild Steel / Acier au carbone | 25–30 |
| Acier inoxydable | 12–18 |
| Aluminum | 60–90 |
| Fonte | 18–25 |
| Brass / Bronze | 30–50 |
| Copper | 25–40 |
| Titanium | 10–15 |
| Tool Steel (Hardened) | 8–12 |
Adjustment Tips
- With coolant/cutting fluid: You can increase tr/min by 10–20% compared to dry percage.
- Deep holes (depth > 3× diameter): Reduce tr/min by 20–30% and use peck percage to clear chips.
- Pilot holes: Use standard tr/min. The avant-trou reduces load on the larger bit.
- Cobalt (M35/M42) bits: Can run 10–15% faster than standard HSS in tough alloys.
- Coated bits (TiN, TiAlN): Revêtements allow 15–30% higher speeds due to reduced friction and heat résistance.
