Details
Economical Carbide Drills for Screw Machine Applications from Rushmore. The tool is designed for applications where a short rigid drill is recommended. Each screw drill bit is designed with two helical flutes having 30 degrees as its helix angle. This construction type goes on to offer faster chip ejection and provide stable drilling conditions. The self-centering split point of 135-degree or 118-degree goes on to further improve penetration. The drill bits have a straight shank for easy holding. Standard style drills are bright to fractional sizes range: 3/64 inch thru 1/2 inch with 135-degree point angle and number sizes range: #1 to #57 with 118 degrees point. The base material used to make the drill bit is solid carbide and the cutting area is coated with Titanium Aluminum Nitride (TiAlN) in select models. These screw drill bits are better than Jobber's drill as shallower holes are easily drilled due to the screw bit's inherent shorter lengths. The product is available in overall length from 1-1/2 inches to 3 inches. The shorter total overall and flute length allows the product to be used in tight spaces and for portable drilling applications that require rigidity. Screw machine bits from Rushmore can drill holes only as deep as their flutes. The available flute length range from 3/8 inch thru 1-1/4 inches for fractional sizes and 3/8 inch thru 1 inch for metric sizes. This USA Made brand offers quality affordable American-made tooling with the superior speed and feed that your applications require. A wide range of Rushmore USA Tools are available here and undergo a strict quality check before they are listed on our product catalog.
