Left-Hand High-Speed Steel Drill Bits


Jobbers' Length Round Shank	Standard

With flutes that spiral in the opposite direction of other bits, these are primarily used to remove stripped screws. Choose a bit that’s slightly smaller than the diameter of the screw’s head. Set your power tool to rotate in reverse. Slowly drill in the center of the screw head, maintaining constant pressure. As the bit penetrates, it will catch onto the screw and reverse it out of the hole. If the screw is badly stripped, you might need to punch a starter hole. Also known as reverse-flute bits. High-speed steel is the versatile choice for drilling most metals.

Diamond-Coated Router Bits for Composites

With a diamond coating, these bits resist wear when used on abrasive materials, making them last about 50 times longer than uncoated bits. Their sharp cutting edges and flute shapes are specifically designed to cut through tough materials such as composites with minimal resistance. This means less strain on your router and more control when cutting, leading to a smooth cut. Bits are made of solid carbide for longer tool life and faster cutting speeds than high-speed steel.

Diamond-Coated Carbide


Drill/Mill Cut Style—Plunge-Cut	Drill/Mill Cut Style—Plunge-Cut, Straight Flutes

Drill/Mill Cut Style—Bits with a drill/mill cut style have a pointed end for easier plunge cuts than square-cut bits.

Plunge Cut—Plunge-cutting bits let you cut directly into the workpiece from above. Other bits are best for operations where the peripheral teeth do most of the work such as trimming, contouring, and finishing.

Straight Flutes—Bits with straight flutes are for general purpose use. They quickly remove material, leaving a rough finish.

Carbide Ball End Mills for Tool Steel, Hardened Steel, and Iron

Ball Cut Style

Flutes have a low helix angle to provide the cutting forces required for difficult-to-machine material, such as hardened steel and iron. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.

Aluminum Titanium Nitride (AlTiN)-Coated Carbide—An aluminum titanium nitride (AlTiN) or aluminum chromium nitride (AlCrN) coating allows them to dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication. This makes these good for aggressive machining while roughing or making interrupted cuts.

Carbide Square End Mills for Honeycomb Panels

6 Flutes

Cut into the sides and make slots in honeycomb panels without damaging any layers. Honeycomb panels are commonly used in aerospace and automotive applications because they’re strong yet lightweight, but these same qualities make them difficult to machine. Unlike normal end mills, these have a left-hand helix and push material downward as they cut, preventing layers of the composite material from separating. The serrated edges break the honeycomb into small pieces, minimizing uncut fibers that can occur in composite material. A diamond coating on these end mills allows them to machine abrasive material, such as carbon fiber, fiberglass, and graphite.

They have a square end for milling square-bottomed slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface. They are good for long production runs. They run twice as fast as other carbide end mills and last up to 30 times longer.

End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.

Fast-Cut Carbide Square End Mills with Chamfer Corner

5 Flutes

A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. They have a square end for milling square-bottomed slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.

Titanium Aluminum Nitride (TiAlN)-Coated Carbide—Titanium aluminum nitride (TiAlN)- and aluminum titanium nitride (AlTiN)-coated end mills dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication.

Fast-Cut Carbide Barrel End Mills

Barrel Cut Style

4 Flutes

Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. Also known as barrel cutters, these end mills create the smooth finish of a ball end mill, but with a tapered cutting surface that removes more material with each pass. They're ideal for 5-axis machining where you need to cut from many angles. Plus, compared to ball end mills, they move farther between overlapping passes (stepover), which decreases machining time and tool wear, so they’ll last longer. All are center cutting, allowing plunge cuts into a surface.
