I. Product Specifications Material: M2 High-Speed Steel (HSS) Dimensions: Total Length: 6.3" (160mm) Cutting Length: 5" (127mm) Cutting Diameter: 5/8" (16mm / 0.625") Design Features: 5 right-hand spiral flutes with precision-ground sharp edges 1/2" round shank with 3 flat sides (tri-flat anti-slip grip) Tapered point for smooth entry into imperfect holes Built-in safe stop mechanism to prevent over-drilling Compatibility: Fits all standard electric/pneumatic drills with 1/2" chuck Certification: ANSI-compliant safety design II. Product Selling Points Industrial-Grade Durability for Demanding Tasks Forged from M2 HSS (64HRC hardness), this reamer withstands 350°C+ friction and resists wear 3x longer than carbon steel tools. Ideal for heavy-duty materials like stainless steel, alloy aluminum, and PVC pipes. 5-Spiral Flute Technology for Precision & Speed The right-hand spiral flutes cut 40% faster than standard reamers while efficiently removing metal chips. Achieve ±0.02mm accuracy in hole alignment, critical for bridge bolts and automotive rivets. Tri-Flat Shank + Safe Stop for Secure Operation The 3-sided anti-slip shank locks firmly in chucks at 2,500 RPM, eliminating slippage. The ANSI-certified safe stop auto-halts drilling at preset depths, preventing workplace accidents. Multi-Material Mastery in Tight Spaces Processes 9+ materials (steel, copper, plastic, etc.) with clean finishes. Compact 6.3" design excels in confined areas like truck chassis or steel beam joints. Pro-Grade Maintenance & Longevity Heat-treated tip resists corrosion. Simply wipe with cutting oil after use—no specialized cleaning required. Includes a bilingual (EN/ES) OSHA-compliant safety guide. III. Usage Scenarios Bridge Construction & Steel Erection Perfect for aligning 5/8" bolt holes in I-beams or smoothing rough-cut rivet holes in structural steel. Ensures OSHA-compliant precision for load-bearing components. Automotive & Truck Trailer Repairs Ream axle mounts, chassis holes, or trailer hitch points without damaging surrounding metal. The tapered point fits uneven holes from prior drilling errors. Industrial Metalworking & Plumbing Enlarge PVC pipe fittings or deburr stainless steel panels. The spiral flutes prevent material galling during prolonged factory use. DIY Home Workshops A go-to tool for hobbyists restoring vintage cars or building custom furniture. The safe stop protects beginners from over-drilling expensive materials. Emergency Maintenance Quickly repair corroded plumbing threads or salvage misaligned bolt holes in machinery. Saves 50% time vs. traditional filing methods. Why Choose SQLMLZ? Engineer-Approved Design: Trusted by welders and mechanics for jobs requiring 5/8" precision. Lifetime Cost Savings: Durable HSS construction reduces tool replacement frequency by 70%. Safety First: ANSI-certified safety features align with U.S. workplace regulations. Note: This tool is for reaming pre-drilled holes only. Always use with cutting oil for optimal results.
