It's ideal for repetitive, high-speed operations where consistent hole sizing and durability are critical-such as panel fabrication or electrical enclosure work.
3. Polished Flute for Clean, Controlled Drilling
The highly polished flute surface allows for efficient chip evacuation and reduced friction, minimizing heat buildup and bit wear. This results in smoother drilling and longer tool life, especially in metalworking environments with frequent tool use.
1. High-Purity HSS Base Material
Manufactured using electric arc furnace (EAF) technology and vacuum degassing, the HSS core achieves excellent purity and metallurgical consistency. The result is high wear resistance and impact toughness, ideal for harsh environments like HVAC, automotive repair, and heavy-duty fabrication.
2. Balanced Hardness and Fracture Resistance
Advanced quenching and tempering give this cone bit an optimal balance of surface hardness and inner ductility. This reduces the risk of chipping, cracking, or premature dulling-especially important when drilling through layered or reinforced sheet metal.
1. Step Design for Controlled Entry and Size Versatility
The stepped profile ensures stable starting on smooth metal surfaces and provides multiple diameter options in a single bit. It's perfect for tasks requiring clean, progressively larger holes-such as conduit installations, cable routing, or switchgear setup.
2. Customizable Specifications Available
We offer custom flute designs, step sizes, and surface coatings (e.g., TiN, TiAlN) tailored to specific applications. These coatings improve hardness, reduce friction, and extend tool life in demanding drilling tasks involving abrasive or high-load materials.
1. High-Efficiency Flute Design for Metal Chip Evacuation
This cone drill bit features a precisely engineered multi-flute structure that facilitates rapid chip clearance from thin metal sheets. The open flute design minimizes heat buildup, prevents material clogging, and ensures stable, vibration-free drilling-ideal for continuous operations on stainless steel, aluminum, and galvanized sheet.
2. Optimized Cutting and Step Angles for Metal Penetration
The cutting angles and step geometry are tailored to reduce resistance and enhance control when drilling through layered or hardened metal surfaces. These optimized angles allow smooth progression through each step, maintaining dimensional accuracy while minimizing burring and edge distortion.
3. Customizable Coatings for High-Load, High-Heat Drilling
Compatible with professional-grade surface treatments to boost durability in challenging applications:
TiAlN Coating: Delivers superior oxidation and heat resistance for high-speed drilling in stainless or alloy steels.
