Solid Carbide Drill Bit

118 degree, split point, solid carbide micrograin drill bit.

Use these bits to drill through hardened steel. Please note carbide bits are fragile and will break easily if mis-used. If you break one, you own both pieces. I've tested these on hardened materials and they will work fine.

These are premium quality, Made in the USA and branded Ultratool. I have just a few of these as they came in by mistake. I have priced them well under my cost just to move them.

Some tips: Use cutting oil and don't let the bit bind in the hole. Clear your chips frequently. If the bit binds up, they will simply spin and crack in half. (I've had two knives leave the shop with hidden broken carbide bits in the tang.) They also don't take side to side torque or twist. Make sure you are straight up and down or square to your work. Unless you have a very steady hand, use them only in a drill press. Don't use a spotting drill to start the hole. Carbide bits will start their own hole easily. If you aren't working in hardened steel, use a normal drill bit. Save these for use only in hardened steel.
