What is Necessary for Mold and Die Deep Hole Drilling?

Deep drilling is a common requirement in the mold and die industry. This process can reach as deep as 50xD and requires specialized tools for high-precision work. The most common deep drilling tool is the single-lip drill. However, other drills are available, such as solid carbide drills, which can be used for smaller components. They are fitted with guiding chamfers to provide good guidance into the bore. Certain pins require very accurate bores. To achieve this, premachining is essential.


Gundrilling is a process used to drill deep holes into molds and dies. These holes can range in size from.25″ to 2.36″ in diameter and are produced with precision and accuracy. The deep drilling process can be performed at high feed rates, reducing costs and lead times. It also provides a range of benefits for the molding industry.

The tools used for gundrilling come in different configurations. For instance, single flute solid carbide gundrills are used in mold and die deep hole drilling. Using these tools will improve feed rates and quality. They are available with different nose geometries and contours for increased precision and repeatability.

Gundrilling machines are designed to drill holes in complex shapes. They are highly productive and easy to operate and can be customized to meet customer requirements. These machines are also available in various levels of automation and are available to cover a wide range of industries and applications.

Another variation of gun drilling is the ejector deep hole drilling system. This method lacks the sealing of the deep hole drilling system to keep metal-working fluid out of the tool. In addition, these machines can also perform oblique boring and discontinuous drilling operations.

In addition to gundrilling, deep hole drilling can use rotating tools. Often, coolant is fed through a hole in the tool to keep it cool during deep hole drilling. The coolant also provides lubrication to the drill’s periphery.

Deep hole drilling is necessary for many mold and die applications. The depth of the hole must be greater than the tool’s diameter. A deep hole can be as much as 150 times the tool’s diameter. The depth of the hole will depend on the way the tool is guided through the machine.


Deep hole drilling in molds and dies requires precision tooling that is designed to drill a deep hole into the die or mold. These tools are expensive to buy and are time-consuming to use. They require a complex fixture setup and require additional labor. Additionally, these machines require highly experienced operators that can drill complex angles. These factors result in higher labor costs per hour.

Deep hole drilling is required in many different types of plastic molds. These holes are necessary for die casting, blow molding, and thermoforming processes. They are also necessary for parts that are designed for medical or aeronautical applications. The depth of a deep hole can be anywhere from 10 times the diameter of the tool, up to 150 times. The depth depends on the design of the hole and the method used to guide the tool through the machine.

Tooling is also needed in micron-scale deep hole drilling operations. These operations require precise control of coolant flow. Using high-pressure, variable-frequency drives and fixed displacement pumps, advanced deep hole drilling machines incorporate the most advanced coolant systems. They also allow for variable flow rate and tool tables.

Tooling is necessary for mold and die deep-hole drilling. Gun drills are the most popular choice for deep hole drilling in the molding industry. This method is popular for producing heater holes and cooling lines. Gun drilling is also used in mold-making processes, where it can reach deeper depths without sacrificing accuracy. Furthermore, gun drilling can reduce costs and lead times because the tool can be used at higher feed rates.

The deep hole drilling machines market is segmented by type, operation, and end-use industry. By end-user industry, the deep hole drilling market is segmented by region.


A number of factors determine the design of a deep hole drilling machine, such as the amount of flexibility and spindle utilization. One of the most critical parameters is the feed rate. These factors should be taken into account when determining the size and type of a machine.

For example, a 5-axis machine has the ability to perform compound angle deep hole drilling, while a 3-axis machine can only do single-axis deep hole drilling. In addition, a machine with a complex setup needs special fixtures and sine plates, which adds additional time to the process. Further, complex molds require highly skilled operators, which translates into a higher cost per hour.

The global deep hole drilling machine market is expected to grow at a significant CAGR during the forecast period. Asia-Pacific is the largest consumer of deep hole drilling machines and is also an industry leader in this market. The region is driven by significant growth in the automotive industry. Automotive companies utilize deep hole drilling machines to produce various components, such as automotive parts. Additionally, titanium fabrication is also a large application for this type of machine.

Machines are required for deep hole drilling for mold and die production. These machines must have vibration dampening capabilities and a lubrication-cooling system. In addition, these machines also require a pilot hole to prepare for the deep hole drilling process. If a pilot hole is not available, a helical drill or a short gun drill can be used instead.

The deep hole drilling machine market is dominated by BTA machines. These machines use a specialized drilling tool attached to a long drill tube to create deep holes in metal. These deep holes can be twenty to eighteen millimeters or more. BTA machines are ideal for large-scale deep hole drilling applications, as they can achieve a deeper diameter than regular twist drills.


Deep hole drilling is a technique that creates holes that are several times deeper than their width. This type of drilling is ideal for die and mold applications that require precision bores. This method will require a specialized touch to ensure that the results are accurate.

Drilling in molds and dies can be costly and time-consuming. For example, gundrilling on a 3-axis machine requires complicated fixture setup, such as sine plates and special fixtures. These processes can take additional time, and they often require highly experienced operators. This results in a higher per-hour cost.

Deep hole drilling machines are used in a variety of industries. These applications include molds for plastics, die casting, blow molding, and thermoforming, among others. Deep hole drilling is also used in the manufacture of aeronautical and medical parts. Deep hole drilling is a critical part of a mold or die manufacturing process. The diameter of the tool used for the process should be more than 10 times larger than the final diameter of the part to be manufactured. The depth of the hole depends on the type of tool and how it is guided through the machine.

The IMSA MFTB series of machines offers good machinability characteristics, and average feed rates of 250-350 mm/min in case-hardening steel. These machines are suitable for production environments and can accommodate a variety of materials and feed rates. These machines also feature interchangeable inserts and braze-welded tools for better consistency.

In addition to this, deep hole drilling machines are also used in the automotive industry. In this industry, the production process requires high precision and output in the shortest time. For example, mold blocks may need to be drilled in two sides at the same time.
