CTA Manufacturing 3840 Large E-Z Chamfer Deburring Tool 18-38mm

The CTA Manufacturing 3840 Large E-Z Chamfer Deburring Tool is designed to service wheel hub studs on light, medium, and heavy-duty applications. Over time, wheel hub studs become damaged or burred from road debris and wear. This tool quickly deburrs the tip and first few threads of wheel hub studs to prevent cross-threading when reinstalling nuts or lug nuts.

Key Features:

• 5-point design for quick and clean deburring
• Working range: 0.7" - 1.5" (18-38mm)
• Single M2-HSS construction - high-speed steel with tungsten-molybdenum for durability and versatility
• Efficiently removes burrs and ridges from bolts, pipe, threaded rod, bar, and dowels
• Creates perfect chamfer for starting nuts or threading dies

Compatible Materials:

• Mild Steel (U.S. Grade 2 / Metric Grade 4.8)
• Hard Steel (U.S. Grade 5 / Metric Grade 8.8)
• Very Hard Steel (U.S. Grade 8 / Metric Grade 10.9)
• Stainless Steel (300 Series)
• Super Hard Steel (U.S. Grade ASTM-A574 / Metric Grade 12.9)

Operating Guidelines:

• Maximum speed: 800 RPM
• Recommended RPM: 18-24mm (600 RPM), 23-29mm (400 RPM), 30-38mm (300 RPM)
• Use slow drill speed with medium pressure; harder materials require higher feed pressure
• Chamfer only the first 1-3 threads on most applications
• Impact drivers will reduce tool life
