Rodman Tools Reaper HSS M2 Drill Bits Target Metalworking Efficiency

The Reaper HSS drill is classified as a Premium-grade product and is supplied with a smooth shank. It is intended for use on metals including steel, aluminum and medium-alloy steel.

M2 high-speed steel is a common choice for general-purpose metal drilling because it maintains hardness at elevated temperatures while offering sufficient toughness for demanding cutting conditions. The DIN 338 designation covers jobber-length twist drills with cylindrical shanks, a format widely used for general drilling work.

The Reaper HSS line incorporates several geometry changes intended to address common metal-drilling issues, including drill walking, chip evacuation and heat buildup.

• Split-point tip: The design provides self-centering capability, helping prevent the drill from sliding across the metal surface and supporting accurate hole placement.
• 135-degree point angle: The wider point angle is intended to allow faster penetration and reduce stress concentration at the start of a hole, which can extend drill life.
• Optimized flute geometry: The flutes are designed for efficient chip removal and to provide a path for cutting fluid to reach the drill point, reducing heat accumulation during cutting.
• Cordless tool compatibility: The series is optimized for use with cordless power tools, with the aim of maximizing work output per battery charge.

The 135-degree point angle is wider than the 118-degree point found on many general-purpose drills. In metal drilling, this geometry is intended to improve stability at entry and reduce the tendency of the bit to wander on smooth or curved surfaces.

The flute design is also intended to support faster chip evacuation, a factor that can affect hole quality and tool temperature. By limiting heat buildup and improving chip flow, the drill is positioned for repeated use in production and maintenance environments.

The Reaper HSS drill is primarily intended for precision drilling in non-alloy steel and medium-alloy steel. Its self-centering tip and chip-evacuation characteristics make it suited to operations that require frequent hole repositioning or moderate hole-location accuracy.

For best results, operating guidance calls for adequate cooling and lubrication during drilling and for tool speed to be set according to material hardness. Regular inspection of the drill point and cutting edges is also advised to maintain hole accuracy and consistent performance.
