JINOO

Why Choose Our Drilling Tools?

JINOO’s Drilling Tools feature innovative geometry design and advanced technology to improve drilling performance.

UMG Carbide Substrate

Our high-performance drilling tools are manufactured from fine-grain carbide substrates with a stable structure and high density.

Oerlikon Coatingtechnologie

For every JINOO’s drilling tool, we have applied advanced coating technology (HELICA, AITiN, TiAIN, PERTURA, and DLC, etc) from Oerlikon Balzers to enhance heat and oxidation resistance.

Self-Centering Point Geometry

Our drilling tools can achieve hole tolerances up to H7 with self-centering point design and optimized chisel edge thinning.

Intern koelvloeistofsysteem

All the drilling tools are designed with efficient internal coolant channels to decrease heat generation and prevent heat buildup.

Geoptimaliseerde fluitgeometrie

Our drilling tools boast a unique flute design to promote the chip flow and maintain stable machining performance.

Reinforced Core Structure

The reinforced core structure can maximize the drilling stability with Vc up to 120 m/min even under extremely heavy cutting loads.

Drilling Tool Geometry Breakdown

1.Solid Carbide Construction for Higher Wear Resistance

Our drilling tools are made from 0.4 μm ultra-fine grain carbide with high transverse rupture strength and high density, minimizing micro-chipping.

2.Oerlikon Coating Technology for Longer Tool Life

AlTiN and TiAlN-based coatings can deliver unmatched heat and oxidation resistance even under high temperatures of nearly 900°C. They can decrease tool friction with minimal edge buildup.

3.Self-Centering Point Geometry for Accurate Hole Positioning

The specialized 140° point angle with the thinned chisel edge can decrease thrust forces by approximately 30%, promoting the precision hole positioning with improved hole accuracy.

4.Internal Coolant Design for Superior Thermal Control

Efficient internal coolant channels can deliver higher heat dissipation and promote the chip flow to maintain drilling stability, even under 12×D drilling depth.

5.Optimized Flute Geometry for Efficient Chip Evacuation

Polished flutes with optimized rake and helix angles can decrease chip packing risk to ensure smooth chip flow.

6.Reinforced Core Structure for Drilling Stability

The reinforced core can deliver higher torsional strength and less tool vibration, improving the hole straightness and roundness.

FAQ about Drilling Tools

Do you provide customized services of drilling tools?

Of course! We furnish non-standard customization of drilling tools beyond standard sizes according to your needs. Factors like materials, diameter, flute length, and coating selection can all be modified to meet your exact requirements, and we will offer you cutting-edge solutions to ensure an outstanding user experience.

What is your MOQ (Minimum Order Quantity) of drilling tools?

For our standard size of drilling tools, we have a minimum order quantity of 5 pieces. Beyond that, if you want JINOO to customize tools for you, there’s generally no minimum order quantity for non-standard tools, and even a small order can be accepted.

What payment methods do you accept for drilling tools?

The payment method of our drilling tools can be flexible; we usually accept bank transfer, credit card, and PayPal.If you have other requirements about the payment method, we can modify it based on your order.

What are the types of drilling tools for CNC machining?

JINOO’s drilling tools contain solid carbide drill bits, deep hole drill bits, step drill bits, and center drills.

Solid carbide drill bits can be applied to variable cutting conditions in general CNC machining and most hole-making applications.

Step drill bits and center drills can also be used to process accurate holes of multiple diameters. Each different drill has a specific cutting purpose, and solid carbide twist drills are perfect for general-purpose machining.

How to choose the right drilling tools for different materials?

You must consider workpiece materials, hole depths, and cutting conditions for your machining.

For most of our drilling tools, we use durable tungsten carbide as a raw material. Combined with wear-resistant coatings (AITiN, Tin, PERTURA, HELICA, etc.), they can greatly increase heat and wear resistance.

Additionally, choose internal coolant drill bits with proper coating to enhance heat resistance if the workpiece materials are highly abrasive, such as fiberglass or composites.

Drilling tools’ geometry is also essential in the tool design. For hard materials, the point angle design should be flatter, approximately 135°, to prevent premature dulling. For soft materials, a sharper angle of 118° or less should be used.

In conclusion, tougher drill bits, usually made from carbide or cobalt, should be used for machining hard materials. For soft and layered materials, drilling tools with a sharper point angle and a unique tip should be used.

What are the differences between Carbide, HSS, and Cobalt Drilling Tools?

Carbide drilling tools are made from tungsten carbide to ensure the exceptional quality of our products.

High-speed steel (HSS) is a tough material commonly used in manufacturing drilling tools at lower prices, and HSS drill bits are suitable for drilling with less rigid setups.

Cobalt is the HSS mixed with a certain percentage of the cobalt alloy (typically between 5% and 8%), which is much harder and heat-resistant than regular HSS. Therefore, cobalt drilling tools can drill stainless steel and other hard steel without dulling quickly.

What are deep hole drilling tools?

Deep hole drills are specialized for drilling holes with depth-to-diameter ratios of more than 10×D. Deep hole drills are commonly designed with internal coolant channels and optimized flutes to deliver smoother chip evacuation with less heat generation.

What drilling tools are best for stainless steel?

Solid carbide drill bits with durable coatings such as TiAlSiN or AITiN are ideal for machining stainless steel. They feature high heat resistance to further decrease the tool wear. We recommend you use solid carbide drill bits with internal coolant channels and optimized point angle design, enabling higher drilling stability in stainless steel machining.
