Chucking Reamer: Size: 4mm, 5mm, 6mm, 8mm, 10mm.
tolerance: H7. Features just the base substrate without any additional coatings, good for wide ranges of applications.
Material: High-speed steel tools are with combination of hardness and toughness for wear resistance, suitable for general purpose applications.
Applications: Cut and remove the thin layer metal on hole surface that has been processed, mainly to improve the precision of holes and reduce the surface roughness.
Features: Straight flute tools allow chips to collect in the flutes and can make shallow cuts in most applications.
How to Use: Chucking reamers (machine reamers) are used on lathes, drill presses and screw machines. Designed for accurate reaming in stainless steel, aluminum, copper, alloy, plastic.

Unique Tapered Reamer - Construction grade reamer set are used to align existing holes prior to bolt or rivet installation. Increased taper for ease in hole entry, especially for drilling holes bigger in pitman arm and steering knuckles..
M2 High Speed Steel - HSS M2 ensures sharp and fast execution in most hard steel material for clean results, while provides good wear resistance in mild steels and non-ferrous materials..
Wide Applications - Works well in free cutting and carbon steels, as well as soft, non-ferrous materials such as aluminum, brass and copper..
Five Grooves Fast Drilling - Reversed spiral push chips forward and are ideal for through-hole applications, reduces the friction, runs cooler, performs well in heat, corrosion and rust resistance..
Safe Straight Shank - Round shank with 3 flats to prevent slipping in the drill chuck, safety flange/ stop collar to prevent the reamer running through the hole..
