Description
This M35 reduced shank drill bit (Silver & Deming style) is designed for drilling larger diameter holes using a standard 1/2" drill chuck. They are engineered for drilling tough, high tensile strength materials such as stainless steel, Inconel, and titanium. Manufactured from premium M35 steel containing 5% cobalt, it delivers increased hardness, superior heat resistance, and extended tool life compared to standard M2 high speed steel. The precision 135° split point ensures fast penetration and reduced walking for accurate metal drilling performance.
- M35 Cobalt Steel (5% Cobalt): Provides increased hardness and heat resistance compared to standard M2 high speed steel.
- 135° Split Point Tip: Self-centering geometry reduces walking and improves drilling accuracy.
- High Red Hardness: Maintains cutting edge strength at elevated temperatures, allowing speeds up to 30% faster than conventional M2.
- Designed for Tough Alloys: Ideal for stainless steel, Inconel, titanium, and other high tensile strength materials.
- Reduced 1/2" shank allows large drill diameters to fit standard drill chucks, increasing the capacity of portable drills and drill presses
- Silver & Deming style drill bit designed for drilling larger diameter holes without requiring larger drill chucks
- Precision Ground Flutes: Promote efficient chip evacuation and consistent hole quality.
What It Is
The Qualtech M35 Cobalt Jobber Length Drill Bit is manufactured from premium M35 cobalt steel containing 5% cobalt for increased hardness and heat resistance over conventional M2 high speed steel.
Designed for drilling high tensile strength materials, M35 cobalt provides improved performance in demanding metal applications where standard HSS bits may lose edge retention.
Why M35 Cobalt?
M35 cobalt steel enhances red hardness - the ability of a cutting tool to maintain hardness at elevated temperatures.
Compared to M2 HSS:
- Greater heat resistance
- Improved wear resistance
- Longer edge life in tougher metals
- Allows drilling speeds up to 30% higher
This makes M35 an excellent choice for stainless steel and difficult alloys.
135° Split Point Performance
The precision 135° split point geometry starts drilling immediately on contact and reduces walking. Sizes smaller than 1/16 have the 118 degree standard point.
The flatter 135° angle is especially effective in harder metals where a standard 118° point may wander.
Applications
The Qualtech M35 cobalt drill bit is well suited for:
- Stainless steel
- Inconel
- Titanium
- Alloy steel
- Tool steel
- Cast iron
- Mild and structural steel
Reduced Shank Design (Silver & Deming Style)
Allows larger drill diameters to fit into standard 1/2" drill chucks, expanding the drilling capacity of portable drills and drill presses.
Frequently Asked Questions
What is M35 cobalt steel?
M35 is a high speed steel alloy containing approximately 5% cobalt. The added cobalt increases hardness and heat resistance compared to standard M2 high speed steel.
How is M35 different from M2?
M35 contains cobalt, which improves red hardness and wear resistance. This allows it to perform better in stainless steel and high tensile strength materials.
What is the difference between M35 and M42 cobalt?
M42 contains approximately 8% cobalt and offers higher hardness and heat resistance than M35. M35 is ideal for general tough metal drilling, while M42 is suited for heavy-duty and high-production applications.
What does “split point” mean?
A split point drill bit features a 135° tip geometry that starts drilling on contact and reduces walking compared to standard 118° drill bits.
What materials can this drill bit drill?
This bit is designed for stainless steel, Inconel, titanium, alloy steel, cast iron, and other high tensile strength materials.
Can this drill bit be used in a hand drill?
Yes. The round shank design is compatible with drill presses, handheld drills, and standard chucks.
What is a reduced shank drill bit?
A reduced shank drill bit has a smaller shank diameter than the cutting diameter, allowing large drill sizes to fit into smaller drill chucks. Silver & Deming drill bits typically have a 1/2" shank for use in standard drills.
