Factory OEM Service HSS M35 Cobalt Straight Shank Twist Drill Bit
Product Description
M35 5% Cobalt Steel Twist Drill Bits Set
A nice-to-have imperial fractional inch bit set for repeated drilling in metals
M35 Grade Cobalt Steel
* Cobalt drill bits are not made of pure cobalt, but rather a steel alloy with certain percent cobalt. The 5-percent alloy is
known as M35 grade. The cobalt increases the strength of the steel and makes it more heat-resistant.

Lowest Cost Per Hole Drilled
* Cobalt bits are more expensive than ordinary HSS drill bits. But if you regularly drill metals, they are a good investment
since they tend to last longer. With an extended life, you can lower the cost per hole drilled.

Tip：
* Tech Tip 1: You shouldn’t drill deeper than 1/2 of the drill bit’s fluting length to have the best drilling performance.
* Tech Tip 2: Don't use M35 cabalt bits on hardened steel, high carbon steel and heat treated steel.
* Please wear safe clothing and eye protection for your safety.

* Please wear safe clothing and eye protection for your safety.
135 Degree Split Point
* 135 degree means less force required to remove metal, compared with lower angles like 90° and 118°.
* Self-centering split point allows you to drill directly to the size needed without any pre-drilling.

Twist Drill Bit Body
* Heavy-duty, fully ground body construction.
* High flow spiral design for the fastest removal rate and for thick material.

Straight Shank
* Straight shank for standard drill chuck, less "walk“ or ”wander“.
* The end of shank is chamfered to allow easy and firm holding.
* Special bronze SST heat and surface treatment.

* Special bronze SST heat and surface treatment.
Be Vertical
* Keep the drill bit vertical with the stuff's surface to be drilled.
* Tilted bit is prone to break during drilling.
* Be sure to make both the bit and the workpiece stable.
* Tilted bit is prone to break during drilling.
* Be sure to make both the bit and the workpiece stable.
Do It Slow
* Drilling metal requires low RPM. Please use a device of which the drilling speed can be adjusted.
* Be careful when you use an electric drill. The RPM could be set too high.
* The thicker the bit, the slower speed should be.
* Be careful when you use an electric drill. The RPM could be set too high.
* The thicker the bit, the slower speed should be.
Stay Cool
* Friction between bit and metal will accumulate an amount of heat.
* It's necessary to use cooling liquid during drilling to keep the bit cool. Otherwise, the bit may fry(melt) or only last a
short time.
* It's both ok to use lubricant oil and to pour water.

Right Drilling Device
* It's highly recommended that you use a drill press to drill thick metals. It's stable, powerful and (RPM) adjustable.
* If a drill press isn't available, electric drill or charging drill will do the job, too. However, it's more likely you'll meet
problems unless you're really experienced.

Instructions for use:
1.Keep the drill bits vertical to the object when drilling, Be sure to make both bit and work piece stable. Tilted bit is prone to
break during drilling
2.Control Speed and Pressure, When using bits with a power drill, it's recommended to use them with low speed and drilling
pressure
3.Drilling metal will accumulate an amount of heat. Necessary to use cooling liquid during drilling to keep the bit cool
4.Thick metals are recommended to be drilled with drill press, which is more stable, and adjustable
Safety instructions:
1.Always wear safety goggles and safety items when drilling
2.Do not wear gloves to avoid hazard of getting caught in the tool and pulling your hand in to get mangled during bit spinning
3.Examine the bits before use for cracks or chips, Do not use damaged or bull bits
