JOBBERS - GENERAL PURPOSE POLISHED: (GP) This style drill is commonly called Jobbers and is of an intermediate length. This Drill is furnished with a 118° point; the smooth surface enhances the chip removal action. The straight shank style is suitable for a number of applications, materials, and can be used on a variety of equipment.

HIGH SPIRAL - HIGH HELIX (FAST SPIRAL) BRIGHT: Designed for the drilling of deep holes and has a 118° point, the high helix and open flutes allow for chips to clear the hole easily. This drill can be used in low tensile strength aluminum, copper, magnesium, and die casting materials. Other materials include soft steels, free machining brass and bronze, stainless steels, and screw machine stock.

DYNA-FLUTE (PARA-FLUTE) BRIGHT: This drill with a 118° point is designed for rapid deep hole drilling, with the ability to operate at faster feed rates with reduced thrust. The special web construction with a wide parabolic shaped flute increases the chip removal rate and allows coolant to flow to the drill point. Due to its special geometry, wood-pecking or periodic retracting is virtually eliminated.

COBALT: Cobalt drills come in a variety of sizes and styles. The cobalt is heat resistant, and they can be used in a number of different applications including, screw machines, and portable drilling applications used for drilling hard, tough materials.

They are used for center holes in work pieces for additional manufacturing operations. Available in HSS, COBALT, and CARBIDE. The Bell type is furnished with a 118° Point Angle and a 60°/120° included angle. Also available in an extra long series.

DRILL & COUNTERSINKS FOR WINSLOW: These are used in tandem to machine the hole that is used to fasten the wiring on aircrafts. Available in HSS and heat resistant COBALT.

CENTER REAMERS: These 3 flute HSS Short Countersinks are designed for countersinking holes for centers, flat head screws, and rivets.

MACHINE COUNTERSINKS: Made of HSS and have 4 flutes. They have added shank length and radial clearance.

HIGH SPEED COUNTERSINKS: The single flute styles are designed for machine and light portable work and work at higher speeds and lower feeds. Other applications include chamfering, deburring, and hole enlarging. The 3 flute style are designed for machine and portable drilling applications, and can be used in chamfering and deburring operations, and should be run at 1/2" to 2/3" the speeds of those recommended for drilling.

Prentice or SILVER & DEMING (S&D): S&D drills are designed with 1/2" shanks, to fit 1/2" drill chucks. Used in both drill presses and portable drills where the drill diameter is larger than chuck available. Provided with a Black-Oxide treatment for abrasion resistance and helps to prevent chip welding.
