Product Details

LD-183 HSS Twist Drill Bit Set 10pc

LD-183 HSS Twist Drill Bit Set provides 10 high-speed steel M2 drill bits in sizes 1mm to 10mm with 135-degree split point for clean, accurate drilling in metal, wood, plastic, and composite materials.

The LD-183 HSS Twist Drill Bit Set is an essential drilling toolkit for professionals, contractors, and serious DIY enthusiasts who demand reliable cutting performance across multiple material types. Each drill bit is manufactured from genuine M2 high-speed steel, a tungsten-molybdenum alloy that maintains cutting edge hardness at elevated temperatures generated during high-speed drilling operations. The 135-degree split point design eliminates walking and skidding on smooth metal surfaces, allowing precise hole placement without the need for center punching. A precision-ground flute design with optimized helix angle efficiently evacuates chips from the hole, reducing heat buildup and extending bit life. The black oxide surface treatment reduces friction and provides mild corrosion resistance for storage durability. The comprehensive 1mm to 10mm size range covers the vast majority of common drilling tasks from delicate electronics work to heavy construction applications. Each bit features a straight shank compatible with standard keyed and keyless drill chucks from 3/8 inch and larger. The organized plastic index case keeps bits sorted by size and protected from damage during transport and storage. Whether drilling steel plates on fabrication jobs, boring holes in hardwood furniture, creating openings in plastic enclosures, or performing general construction drilling, the LD-183 HSS twist drill bit set delivers professional-grade results at wholesale pricing.

FAQ

What is the difference between HSS and cobalt drill bits?

HSS (High Speed Steel) bits are suitable for drilling most metals, wood, and plastics. Cobalt bits contain 5-8% cobalt alloy for superior heat resistance and are recommended for harder materials like stainless steel and cast iron. The LD-183 uses M2 HSS suitable for general metal drilling.

Can these drill bits be used with an impact driver?

No, standard twist drill bits are designed for rotary drilling in drill chucks. Impact drivers deliver hammering action that can damage standard drill bits. Use impact-rated drill bits or switch to a standard drill for rotary-only operation.

What is the recommended drilling speed for different materials?

For steel: use lower speeds (800-1500 RPM for 6mm bit). For aluminum: medium speeds (1500-2500 RPM). For wood: higher speeds (2000-3000 RPM). Always use cutting fluid when drilling metal to extend bit life.

How do I prevent the drill bit from breaking?

Apply steady moderate pressure without forcing. Use the correct speed for the material. Withdraw periodically to clear chips. Never bend or apply lateral pressure to the bit. Ensure the workpiece is securely clamped.
