FOCMKEAS Hand Reamer 3/4" Alloy Tool Steel 9Crsi H8 6 Straight Flutes Hand Milling Cutter Tool

• 【SIZE】Cutting Dia.: 3/4", Square shank side:15mm/0.59"; Tool flute length: 100mm/3.94"; Overall length: 195mm/7.68".Package include 1 piece.
• 【MATERIAL】Made by 9Crsi alloy tool steel, Hard and durable，reaches H8 level of drilling accuracy, reduces surface roughness of workpieces.
• 【CHAMFERED ANGLE DESIGN】Chamfered Angle in the bottem provide orienting effects, ensure axis position and roundness.
• 【FEATURE】: Reamer can be hand operated by use of wrenches and used for light cut, repair work, removing stock or simply for enlarging holes.
• 【APPLICATION】Designed for accurate reaming in aluminum, cast iron, copper, magnesium alloy, plastic etc.

Can be hand operated by use of wrenches. Great for light cut, repair work, or simply for enlarging holes. Always keep reamers clean, and used with machine oil for long service use. 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.Used for semi-finish machining and finish machining of holes. Reamers are with 4 or more cutter teeth. Finished product can be smooth, intact and more beautiful. Reamers can be used to process holes in small cuts based on guiding function, such as: holes with diameter tolerance in ≤IT8; holes with requirements in surface roughness (≤Rz12 generally); holes with requirements in roundness tolerance; holes with requirements in cylindricity; stepped holes (different diameter holes on the same axis); series holes (diameter holes on the same axis) with requirements in high coaxality.
