Key Features

• Premium M35 Cobalt Construction: Manufactured from High-Speed Steel containing 5% Cobalt (HSS-Co), these bits achieve a Rockwell Hardness of up to 67 HRC. This advanced composition provides superior heat and wear resistance, allowing them to cut through hard metals like stainless steel, cast iron, and titanium alloy up to 12x longer than standard HSS bits. Precision 135° Split Point: Features a self-centering 135-degree split point tip that penetrates hard materials immediately with less pressure. This design eliminates "walking" or wandering on the surface, ensuring a precise start without the need for a center punch or pilot hole. Fully Ground for Efficiency: Unlike roll-forged alternatives, these bits are fully ground from solid hardened steel. This precise manufacturing process ensures accurate diameter concentricity and sharper cutting edges. The precision-ground dual flutes provide smooth, efficient chip removal to prevent overheating. 13-Piece Metric Size Range: A comprehensive set covering common metric sizes for tapping and general drilling: 1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.5, 4.8, 5, 5.5, 6, and 6.5mm. Includes specific sizes often required for rivets or pre-threading holes (e.g., 3.2mm, 4.8mm). Professional Metal Index Case: Housed in a durable, heavy-duty red metal index case rather than plastic. The case features a clearly labeled metal holder that tilts out for easy access and organization, protecting the bits from damage during transport and storage in rough workshop environments.
