Why Gun Drills by Sunshine are Better

Gun drills find their usage in hole application of 0.5 to 50 mm in diameter. These are actually deep hole drilling tools that carry out all of the major drilling applications. At Sunshine, we provide the best quality gun drills designed by experts and then choosing based on quality and performance. We make sure that the demands of the customers are met with our modern tools for high feed in this highly challenging environment of the industry. We have achieved a strong engineering level relationship with our users over the years.

Our scope of supply includes single flute and double flute gun drills along with various designs of coolant holes. We also provide solid carbide, carbide brazed, and indexable insert gun drills. Our focus is on providing solutions that are optimized to the needs of our customers. Along with the vast variety, our experience in the sector helps us choose a better gun drill for your exact application in the first time.

Our specialized coolant hole and flute designs accentuate the rate of chip removal thus helping in obtaining faster machining parameters and better bore finish.

For threading long parts with small diameter in various exotic materials like titanium, nickel-based alloys, thread whirling is used. Our collection of thread whirling tools allows the manufacturing of small-diameter, long threads used on Swiss-type machines. With whirling holders and inserts a variety of medical parts like bone screws, dental implants and many automotive parts are produced.

Our thread whirling tools possess the following features:

1. Enhanced Productivity: As thread whirling is done in a single motion, machining times are shorter. Also, such tools allow operation under high feed rates.
2. Faster Setup: With Thread whirling the need for special support devices is eliminated and even the initial R&D cost is reduced.
3. Longer Tool Life: In comparison to the single-point tools, the whirling inserts have a stronger cutting edge and the cutter side clearance is attained via whirling spindle rotation. There’s no need to relieve material under the cutting edge and this offers a longer tool life.
4. Offers Support for Large Helix Angles: By adjusting the whirling unit the large helix angles can be compensated.

There are various advantages that the thread whirling process offers incorporating precision results compared to other high-quality trading methods like scheduling and thread grinding. With the thread rolling process you can achieve enhanced surface finish which is a result of the distinctive tangential cutter path and we enhanced rigidity. Due to longer to life and reduced cheap load, burrs are also minimized.

If we compare thread whirling to the thread milling at 0-degree thread wall, then you will find finish pattern in thread whirling improved. This is due to the tangential radial entry and exit of the cutter that leaves a very uniform pattern.
Benefits of thread whirling:

1. Single motion threading from stock diameter improves productivity and decreases cycle time
2. There’s no need of finishing treatment
3. Can easily machine high-quality threads on long and slender components without any risk of vibrations and bending
4. Accurate threads are produced by tilting the whirling ring
5. Offers good chip control and allows more productive machining.

Chemfering tools



Our chamfering and spot facing tools are designed to chamfer, front and dark spot face and deburr several different services in

a single motion. This implies that the complex front and back spot facing routine can be easily carried out in an individual machining cycle. This also allows doing the routine as a part of a repeat process production line, thus decreasing the time required for completing the procedure and hence saving the cost.

Our tools come with a versatile wing replacement system that makes them even more cost effective. By offering automatic c

hamfering applications via tools, we focus on modern industry needs. Additionally, our tools are very efficient and productive while being sensitive to the environment. The extra procedures can be eliminated and 100% consistency can be maintained

between the critical dimensions with our high quality tools. By reducing the risk of mechanical failures and human error we try to offer only the best through our chamfering tools. As our products are imported from USA and Europe, you don’t have to worry

about any of your chamfering and spot facing operations. There’s no need of manual benching or interpolation.

With our chamfering tools you can enjoy the


• An easy-to-use tool for the deburring and chamfering through holes on the top and bottom.
• You don’t have to reverse the spindle, indexing and dwelling part.
• It is an ideal option for high volume manufacturing.
• The blades can be changed easily to in

crease the efficiency of the production.
• With a solid body design the user gets the highest durability of any deburring tool.
• Long life is by the coated carbide blades.
