13 Sizes Steel Drill Bits Set: The set includes 13pcs of M35 cobalt steel twist drill bits: 1.5mm, 2mm, 2.5mm, 3mm, 3.2mm, 3.5mm, 4mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm, 6.5mm, fits the majority of power drill currently on the market and come with a portable plastic bag for easy storage and organization.
M35 Cobalt Steel: These drill bits also contain 5% Cobalt, which increases wear-resistance and durability for much faster cutting and extra longer life span.
For Metalworking: Perfectly suitable for cutting stainless steel, die steel, aluminum alloy, cast iron, copper, galvanized pipe, plastic, wood or other softer/hard metals. × Not for glass, ceramic, high carbon steel, heat-treated steel or hardened steel.
Twist Drill Bit Body: Fully Ground spiral groove design clears particles quickly, decreases friction and heat for a faster and cooler drilling performance.
135° Split Point: 135° Quick-Cut Point with straight shank prevents ””walk”” or ””wander”” and makes drilling precise with less pressure. Fit for standard drill chucks and regular round collet chucks.

Warm Tips:
1. You shouldn’t drill deeper than 1/2 of the drill bit’s fluting length to have the best drilling performance.
2. Don’t use these bits on hardened steel, high carbon steel and heat treated steel.
3. Please keep the drill bit vertical with the surface of object to be drilled. And Ensure the stability of the drill and the workpiece, tilted bit is prone to break.
4. Pay attention to the power of the charging drill.  Too low power may make it impossible to drill.
5. Drilling metal requires low RPM, it’s recommended to use a device of which the drilling speed below 1000RPM.
6. To avoid breaking, thick metals are recommended to be drilled with drill press, which is more stable, and adjustable.
7. Friction will accumulate heat between bits and work piece. Please be aware of the heat, add water or coolant during drilling to keep the bit cool if necessary.
