6.5mm Straight Shank Twist Drill

Item No:W59019

 

1.Key Structural & Material Features

Straight Shank Design: Smooth cylindrical shank compatible with hand drills, bench drills, and CNC machines (chuck capacity typically up to 13mm), enabling easy installation and stable operation.

Twist Flute Geometry: Helical flutes facilitate continuous chip evacuation during drilling, reducing friction and preventing clogging, especially in deep-hole applications.

Material Versatility: Commonly made from high-speed steel (HSS) for general-purpose use, or cobalt-infused HSS for harder metals, ensuring durability and heat resistance.

 

2.Applications in Diverse Materials

Metal Processing

Mild Steel & Non-Ferrous Metals:Drills 6.5mm holes in low-carbon steel plates (up to 15mm thickness), aluminum, copper, or brass for:

Mounting M6 screws (threaded hole diameter ~5.2-5.5mm, with 6.5mm often used for clearance holes or pilot holes in thick materials).

Fabricating metal brackets, machine components, or automotive parts (e.g., engine mount holes).

Stainless Steel & Hard Alloys:

With proper lubrication (cutting oil) and reduced speed (800-1,200 RPM), suitable for drilling stainless steel sheets or cast iron components, though heavy-duty tasks may require cobalt bits.

 

Woodworking & Carpentry

Hardwood & Softwood:Creates deep 通孔 (through-holes) or blind holes in lumber, plywood, or MDF for:

Installing large wood screws, dowels, or bolts in furniture (e.g., connecting beams in wooden structures).

Drilling cable channels in cabinets or creating holes for decorative elements (e.g., wooden handles with through-holes).

Composite Materials: Works on particleboard, OSB (oriented strand board), or fiber cement boards for construction framing or DIY projects.

 

Plastic & Non-Metallic Materials

Rigid Plastics:Drills clean holes in PVC, acrylic, or ABS sheets for:

Mounting plastic fixtures in DIY projects (e.g., garden planter drainage holes, model railway components).

Creating ports in electronic enclosures for wires or connectors.

 

Building & Construction Materials:

Suitable for gypsum board, plaster, or lightweight concrete (with masonry bit adapter) to install anchors for shelves, light fixtures, or curtain rods.

 

 

3.Industrial & Practical Use Cases

Manufacturing & Engineering

Mechanical Engineering:

Drills 定位孔 (positioning holes) in machine parts like gears, flanges, or molds for precise assembly.

Creates holes for pins, shafts, or bearings in mechanical systems (e.g., in conveyor belt components).

 

Electrical & Electronics:

Drills holes in metal switchgear panels for cable glands or in plastic control boxes for button installations.

 

Construction & Renovation

Structural Drilling:

In concrete or brick walls (with 冲击钻 mode), drills 6.5mm holes for M6 expansion bolts to secure heavy brackets, pipes, or metal frameworks.

 

Carpentry & Joinery:

Used in timber framing to drill pilot holes for large nails, preventing wood splitting in hardwood beams.

 

DIY & Hobby Projects

Home Improvement:

Fixes decking by drilling new screw holes or creates mounting points for wall-mounted tools in workshops.

 

Crafts & Models:

Drills holes in large-scale models (e.g., RC car chassis, model aircraft wings) for axles, hinges, or wire routing.

 

Art & Metalwork:

Creates holes in sheet metal art pieces for hanging or in leathercraft for threading thick cords.

 

4.Technical Advantages & Operational Tips

Speed & Lubrication Recommendations:

Metal: 800-1,500 RPM with cutting oil to prevent overheating (e.g., drilling steel at 1,000 RPM).

Wood/Plastic: 2,000-3,500 RPM; clear chips regularly to avoid jamming (e.g., plywood at 2,500 RPM).

 

Precision & Safety:

Use a center punch to mark hole positions on smooth surfaces (e.g., metal sheets) to prevent bit wandering.

For deep holes (>30mm), withdraw the bit periodically to clear chips and cool the tip.

 

Compatibility & Maintenance:

Fits most handheld drills (e.g., cordless drills) and benchtop tools. Store in a dry place to prevent rust; resharpen HSS bits when dull for extended lifespan.
