Since 1925, Walter Tools has been manufacturing high-quality precision and machining tools for applications in construction, automotive, energy and aviation industries. The Walter Tools catalogue includes drill bits, end mills, chucking reamers, grooving tools, tool holders and thread mils. The brand's Xtreme type jobber drill bits are designed in accordance with OSHA & ISO certifications and feature surface-treated construction, thereby ideal for creating holes in circular cross-sections with added hardness and wear resistance. These carbide drill bits are capable of providing better structural rigidity, as compared to high-speed steel, and have spiral flutes constructed with a higher flute angle to efficiently remove the chips. To enlarge an existing hole for accurate fastener installations, Walter chucking reamers allow easy mounting on drill presses, lathes and screw machines with the help of a straight or morse taper shank and feature a 45 degrees chamfer on the cutting edge to provide maximum precision, as the reamer enters the hole. Choose from a wide range of these reamers and other related brand products, like end mills, grooving tools, boring bars, tool holders and tool holder accessories on Raptor Supplies.
