The Challenge: In large-scale industrial projects, needing an uncommon size like 53mm or 75mm often halts production while a specialized tool is ordered.
The Result: Significant labor costs and project delays.
Our Solution: This 23-Piece Collection provides every critical industrial increment from 16mm to 100mm, ensuring you never have to compromise with "near-fit" sizing again.
Material Limits: Standard HSS and Bi-Metal saws fail when boring through thick-walled stainless steel or hardened structural beams due to thermal rounding.
Structural Play: Most large-bore sets lack the concentricity needed for precision fitment. Our Titan series maintains a Whole Length of 80mmwith a reinforced 10mm(2/5") shank to ensure absolute stability at any diameter.
| Diameter (mm) | Equivalent (inch) | Diameter (mm) | Equivalent (inch) |
| 16mm | 5/8" | 45mm | 1-25/32" |
| 18mm | 45/64" | 48mm | 1-7/8" |
| 20mm | 25/32" | 50mm | 1-31/32" |
| 22mm | 7/8" | 53mm | 2-5/64" |
| 25mm | 1" | 55mm | 2-5/32" |
| 26mm | 1-1/32" | 60mm | 2-3/8" |
| 28mm | 1-8/64" | 65mm | 2-9/16" |
| 30mm | 1-3/16" | 70mm | 2-3/4" |
| 32mm | 1-1/4" | 75mm | 2-15/16" |
| 35mm | 1-3/8" | 80mm | 3-5/32" |
| 38mm | 1-1/2" | 100mm | 3-15/16" |
| 40mm | 1-7/12" |
Heavy MEP Infrastructure: Precise sizing for M16 through M100 cable glands and secondary conduit transitions in massive industrial distribution hubs.
Marine & Petrochemical: Engineered for continuous boring through thick-walled 316 Stainless Steel pipes and pressure vessel housings.
Structural Steel Engineering: The ultimate tool for creating bolt-clearance holes in heavy-gauge I-beams and structural columns where HSS tools reach their thermal limits.
Material Compatibility: Optimized for Stainless Steel (5mm or less), Iron Plate (25mm or less), Aluminum Alloys, and Cast Iron.
RPM Management:
16mm to 30mm: 400 - 600 RPM
32mm to 55mm: 200 - 350 RPM
60mm to 100mm: 80 - 150 RPM (Low-speed/high-torque protocol is mandatory for large-diameter carbide longevity).
Monoblock Precision: The one-piece integrated design eliminates play, delivering a Total Indicator Runout (TIR) of 0.10mm or less.
YG8 Carbide Hardness: Tips are vacuum-brazed to the alloy body for a permanent bond that survives high-impact industrial boring.
Centering: Includes a 135-degree split-point center drill and high-tension ejection spring to ensure the axis remains true.
Question: Why is a 23-piece set preferred over smaller kits for industrial sites?
Answer: Industrial projects often require non-standard diameters for specialized sensors and heavy-duty conduits. This set eliminates the "selection gap," ensuring you always have the exact fit for PG and M-series standards (from 16mm to 100mm) without needing to order individual bits mid-project, which saves significant labor costs.
Question: Can this TCT set handle 316 Stainless Steel thicker than 5mm?
Answer: Yes, but it requires a strict low-RPM strategy and constant lubrication. While the YG8 carbide tips are designed to maintain hardness at extreme temperatures, managing heat through speed control is essential to prevent tip fractures when boring through heavy-gauge stainless steel.
Question: What is the specific mechanical advantage of the 10mm Triangular Shank?
Answer: Unlike round shanks that can slip under the high torque of a 100mm cut, the triangular design provides three flat contact surfaces for the drill chuck. This ensures a 100 percent mechanical lock, preventing tool spin in the chuck and protecting both the cutting edge and the operator from sudden kickback.
