High-Quality Finish, H7 Precision Tolerance, and Cobalt HSS-E

Machine reamer featuring slow left-hand spiral flutes and a straight shank, 10.00 mm diameter, 133 mm total length, 38 mm flute length, and 87 mm neck relief length; manufactured according to DIN 212 standards. For reaming precise holes to H7 tolerance; made of cobalt-alloyed HSS-E with a bright finish for machining carbon steel, alloy steel, gray cast iron, malleable cast iron, wrought aluminum, cast aluminum, copper, or copper alloys.

Technical Advantages

• HSS-E (Cobalt) High-Speed ??Steel: Maintains cutting hardness and edge sharpness even at high temperatures, reducing premature wear.

• Standardized H7 Tolerance: Ensures the maximum dimensional precision required by industrial technical drawings.

• Left-Hand Helix (Right-Hand Cut): Prevents grabbing at the hole entry and ejects chips in the direction of the feed to avoid scratching the internal walls.

• DIN 6535 HA Cylindrical Shank (Tolerance h6):Allows rigid and impeccable clamping in ER collet holders, hydraulic chucks or thermal cones.
