Chamfering Knife 3 Flute 90-Degree Countersunk Drill 4.5-30mm Hss Deburring Drill Expanding Inner Hole Metal Drilling ToolSpecifications: 4.5mm 6.3mm 8.3mm 10.4mm 12.4mm 14mm 16.5mm 18mm 20.5mm 23mm 25mm 30mmThis product is a precision tool, which is suitable for machining centers and bench drills. The use of electric drills is prohibited. Low-precision machining equipment such as bench drills may vibrate the knife. It is recommended to use a single-edged chamfering knife.Products are divided into single-edged, 3-edged, and 3-edged cobalt.Features of single blade: smooth and rounded chamfer. It is suitable for high-precision workpieces, suitable for processing soft materials, thin materials, and easy to deburr. It is more suitable for beginners.Features of 3 blades: Three blades are cut at the same time, which is more efficient and more wear-resistant. It is suitable for chamfering and deep cutting of hard materials such as long die steel, stainless steel and rails.The characteristics of the 3-blade containing cobalt: the cobalt-containing coating is more durable and wear-resistant. It is suitable for chamfering and deep cutting of hard materials such as long die steel, stainless steel and rails.==========Diameter : 4.5mm 6.3mm 8.3mm 10.4mm 12.4mm 14mm 16.5mm 18mm 20.5mm 23mm 25mm 30mmOrigin : ChinaModel Number : 1/3 FluteMaterial : High Speed SteelOverall Length : 40mm-71mm

• 【Material】: Made from high-quality materials (such as HSS or TiN-coated steel), these tools offer excellent heat resistance, corrosion resistance, and rust prevention.
• 【Precision Machining Tools】: Available in a variety of common chamfer angles, such as 90°, 60°, and 120°, these tools are suitable for precision machining and can accommodate various chamfer sizes and depths.
• 【Chamfering and Deburring】: Creates a beveled edge (chamfer) at a specific angle on the openings or edges of materials such as metal, or removes sharp burrs left after machining, making the workpiece safer and more aesthetically pleasing, and preparing it for subsequent processes such as tapping.
• 【Efficiency】: This wood and metal drill bit features a one-piece design, making it easier to handle chips generated during the chamfering process and preventing tool clogging that could reduce work efficiency.
• 【Versatile Applications】: Suitable for a wide range of materials, including aluminum, brass, wood, and plastic, making it an ideal choice for various projects.
