  • Micro 100 brand recognised for precision machining tools

1/2-Inch Carbide Spade Drill

The Micro 100 SD-500 is a solid carbide spade drill bit with a 1/2-inch cutting diameter and a 118-degree point angle. It features a bright uncoated finish and a decimal equivalent of .5000 inches. This accessory is built for machinists and maintenance teams drilling precise holes in tough materials.

Fits Standard Tool Holders

The straight-shank design allows the bit to be secured in common drill chucks, collets or CNC tool holders without proprietary adapters. Its rigid carbide construction reduces deflection, freeing the operator from frequent repositioning and enabling faster cycle times on repeatable hole patterns.

Upgrades From High-Speed Steel Bits

Carbide replaces conventional high-speed steel when longer tool life and higher cutting speeds are required. The jump is worth it for production runs where reduced tool changes outweigh the higher initial cost, but not for occasional low-volume drilling in soft metals.

Questions about this item

How does the 118° point angle hold up under sustained drilling?

The 118° point angle on this carbide spade drill is designed for general-purpose drilling and maintains its geometry during continuous use in appropriate materials.

What heat or vibration should I expect when running this bit all day?

Carbide construction resists heat buildup better than high-speed steel, but sustained high-speed drilling will still generate heat; use proper cutting fluid and speeds for the material.

What shank size or holder does this 1/2 in bit need to fit my machine?

This spade drill has a 1/2 in cutting diameter and requires a compatible tool holder or collet that accepts the shank configuration specified for Micro 100 SD-500 series bits.
