Why Choose Our Multi-Purpose Drill Bits?

JINOO’s D2200-Series Multi Purpose Drill Bits are optimized to achieve improved cutting performance in a wide variety of materials.

extended tool life of multi purpose drill bits

Solid Carbide Construction

Our multi-purpose drill bits are manufactured from 0.4 μm ultra-fine carbide substrates with a uniform grain size.

improved change efficiency of multi purpose drill bits

Oerlikon HELICA Coating Technology

Our multi-purpose drill bits can demonstrate superior performance with the use of Oerlikon’s high-performance HELICA coating technology.

machining consistency of multi purpose drill bits

140° Point Angle Design

Multi-purpose drill bits are designed with a 140° point angle and precisely ground point geometry.

Wide material compatibility of multi purpose drill bits

Cutting Edge Preparation

Solid carbide multi-purpose drill bits require cutting-edge preparation to achieve micro-honed edges.

Promoted hole wall quality of multi purpose drill bits

Reinforced Web Core

The reinforced web core enables stable cross-sectional strength with higher core thickness.

Helical Flute Design

The helical flutes have precisely ground profiles and smooth surface finishes.

Multi Purpose Drill Geometry Breakdown

1.0.4 μm Solid Carbide Construction for Higher Hardness

Multi-purpose drill bits are made from 0.4 μm tungsten carbide with excellent hardness and toughness to withstand higher cutting loads.

2.HELICA Coating Technology for Wear Resistance

Featuring high-performance HELICA coatings, our drill bits can deliver improved wear resistance and tool rigidity with minimal flank wear and edge buildup.

3.140° Point Angle Design for Stable Entry

The 140° point angle is optimized to evenly distribute axial and radial cutting forces with less tool vibration and higher positioning accuracy.

4.Cutting Edge Preparation for Lower Torque

Honed cutting edges are precision ground to remove microscopic defects, decreasing cutting torque with higher hole roundness.

5.Reinforced Web Core for Superior Rigidity

The drill core features higher cross-sectional stiffness to improve tool rigidity and resist tool vibration.

6.Variable Helical Flutes for Smooth Chip Flow

Featuring helix angles from 24° to 32°, helical flutes can optimize the chip flow with less chip packing risks and heat generation.

7.Shortened Chisel Edge for Less Thrust Force

The chisel edge is shortened to about 2% to 6% of the tool diameter, which greatly decreases the extrusion zone to reduce thrust force and improve self-centering.

8.7°-15° Relief Angles for Reduced Heat Generation

The relief angles typically range from 7° to 15°to minimize the tool contact, decreasing the friction and flank wear to reduce heat generation.

Multi-Purpose Drill Bit Application Cases

84% Reduced Costs in Industrial Valve Body Machining

Background

A well-renowned industrial component manufacturer produced stainless steel valve bodies in heavy-duty machining. The previously used drill bits achieved poor chip evacuation, requiring frequent tool changes.

Challenge

Workpiece: Industrial Valve Body
Material: AISI 304 Stainless Steel
Hardness: 180–210 HB
Hole Type: Through Hole
Hole Depth: 3×D
Requirement: Smooth chip evacuation with less chip pecking and superior hole consistency.

Solution

Tool Used: D2200-Series 3D Multi-Purpose Drill Bits
Coolant Type: Internal Coolant
Machine Tool: Vertical CNC Machining Center
Spindle Speed: 3,800 rpm
Feed Rate: 0.18 mm/rev (≈684 mm/min)

Results

The tool life was extended by nearly 66% with more than 18,000 holes created in manufacturing, and excellent hole quality could be achieved with surface finishes typically from Ra 1.6 to 2.0 μm.

Testimonials

“Our company has over 200 sets of CNC machinery to support our daily production. We are afraid that multi-purpose drill bits are getting worse, leading to delays in overall production and high machinery adjustment fees. However, when I tried the multi-purpose drill bits from JINOO, the universal performance amazed me a lot. When I processed the crankshaft, the other drills could only drill 80 holes, but JINOO’s multi-purpose drills were able to drill nearly 240 holes, which is cost-effective enough with excellent chip evacuation. JINOO is the reliable custom CNC drill bits supplier you can trust.”

How long does delivery usually take for JINOO’s Multi-Purpose Drills?

If you want to buy the standard multi-purpose drill bits in stock, the delivery time will typically be within 3-5 business days, while the delivery time of custom drills should be finalized according to specific tool parameters.

Which payment methods does JINOO accept?

There are various payment methods for our clients to choose from, including T/T, credit card payments, and other payment methods. You can contact our sales team with your requirements.

What specifications are available for JINOO’s Multi-Purpose Drills?

JINOO has set 3xD and 5xD for our multi-purpose drill bits, with both internal coolant and external coolant channels available. The standard cutting diameters range from 3 mm to 20 mm. If you require a smaller or larger one, we could also customize it based on your needs. We have also applied advanced coatings from Oerlikon to improve wear resistance and extend tool life. You can send us your machining requirements or CAD graph, and our professional technical teams will design for you!

Which one is better, the D2100-Series General Purpose Drill Bits or the D2200-Series Multi Purpose Drill Bits?

Both series are tailored to specific machining requirements and suitable for different applications: The D2100 series is our long-standing solid carbide drill bits, designed to handle diverse materials such as steel, stainless steel, and cast iron with stable performance.

For the D2200 series multi-purpose drills, we upgrade the new geometry design of J-type groove, curved cutting edge, and dual-plane rear angle to achieve higher efficiency, with the following main advantages:

Excellent chip evacuation & Less chip build-up.
Reduced cutting resistance, increased feed rates, & Improved efficiency.
Better surface finish & Dimensional accuracy.

How can I maintain D2200 multi-purpose carbide drill bits for long-term use?

Multi-purpose drill bits require proper maintenance to prolong their drill bit life. After every use, remember to clean them promptly. Regular re-sharpening is also essential. Using coolants and lubrication properly with moderate speeds and feeds can help you ensure drilling stability and dimensional accuracy.

What is the recommended drilling speed for the D2200 multi-purpose drill bit?

The most suitable drilling speeds for multipurpose drill bits are based on the workpiece material. Combined with steady feeds, moderate RPM is required for multi-purpose drill bits for steel, while higher speeds are suitable for drill bits for aluminum or soft metals.
