HSS Steel Drill Bit 1.1 mm 🛠️

Engineered for precision drilling and long service life, this High-Speed Steel (HSS) drill bit delivers clean, accurate holes across metals, wood, and plastics. Suitable for both professional workshops and DIY benches, it’s a dependable choice for enclosure work, chassis fabrication, and general electronics projects—including mounting and panel work for  other microcontroller modules.

Key Features ⚙️

• Durable HSS construction for wear resistance and extended tool life.
• 1.1 mm diameter for fine, accurate holes in a wide range of materials.
• Broad compatibility with most standard drilling machines, drill presses, and rotary tools.
• Ideal for metal, wood, and plastic; perfect for enclosure cutouts, brackets, and light fabrication.
• Great for electronics builders: create precise mounting holes for sensors, headers, connectors, and low-voltage project enclosures.

Technical Specifications 📐

• Material: High-Speed Steel (HSS)
• Diameter: 1.1 mm
• Length: Varies by model
• Weight: Varies by model
• Color: Silver

Applications 🔧

• Electronics and prototyping: enclosure and panel drilling for  microcontroller modules; mounting holes for electronics components.
• Metalworking: thin sheet, light brackets, and small hardware fabrication.
• Woodworking: fine pilot holes, model making, and furniture detailing.
• Plastics: acrylic, ABS, and project boxes for low-voltage systems and control panels.
• DIY and hobby: crafts, RC models, and general-purpose drilling.

Usage Tips for Best Results 💡

• Use a center punch or pilot hole to minimize walking and improve accuracy.
• Select appropriate speed and feed: slower for metals, faster for wood/plastic; clear chips frequently.
• Apply cutting fluid or light oil when drilling metals to reduce heat and extend tool life.
• Secure the workpiece and consider a drill press for tighter tolerances.
• For abrasive PCB materials (e.g., FR-4), carbide bits are recommended; if using HSS, feed lightly and manage heat.
