DearChan Tubing Deburring Tool for 3/16"–1/2" Tubing — 3-Blade Rimming Tool for Brake, Fuel & Transmission Lines

This compact metal tool removes burrs and sharp edges from brake, fuel, transmission, and coolant lines as well as general tubing made from stainless steel, mild steel, copper, aluminum, and PVC. Built for garage technicians and DIY mechanics, it prepares tube ends for reliable flares and leak-free fittings by delivering consistently smooth internal and external edges.

How does this tool improve tubing preparation?

Removing burrs prevents metal shards from contaminating fluid lines and ensures flares seat properly. The tool’s three cutting edges trim and chamfer the inside and outside of the tube in one pass, reducing the need for repeated filings and cleanup.

• Three precision blades for internal and external deburring
• Single-hand operation speeds prep time
• Compatible with common tubing materials to avoid cross-contamination

What tube sizes and materials are supported?

It accepts tube outside diameters from 3/16" (4 mm) up to 1/2" (14 mm), covering the sizes most often used in automotive brake, fuel and transmission routing. The cutting geometry and material selection let it work on soft metals and plastics without deforming the tube end.

• Fits 3/16" to 1/2" (4–14 mm) OD tubing
• Works on stainless steel, mild steel, copper, aluminum, PVC
• Suitable for brake, fuel, coolant and transmission lines

Is this tool durable and safe for workshop use?

DearChan constructs the tool from hardened metal to resist corrosion, retain edge geometry, and withstand repeated use. An anti-slip handle and balanced design give you control during fast rotations, reducing slips and potential damage to the tube or surrounding parts.

• Corrosion-resistant metal body for long service life
• Anti-slip grip for steady handling during deburring
• Stable cutting action minimizes deforming thin-walled tubing

How quickly will this tool get the job done?

Its three-blade rimming action and ergonomic grip let you clean a tube end in seconds, making it ideal when prepping multiple lines. Using this tool before flaring or welding shortens setup time and reduces the number of rework passes.

• One- or two-turn passes deliver a clean edge
• Saves time compared with hand files and deburring stones
• Reduces risk of leaks by improving flare seating surface

Who is this for: The DearChan Tubing Deburring Tool is intended for professional mechanics, automotive restorers, HVAC technicians, and competent DIYers who install or repair brake, fuel, transmission, and coolant tubing. If you routinely flare or join metal or plastic tubing and need consistent, clean tube ends without expensive equipment, this compact, durable tool is a practical addition to your toolkit.
