Makita D-17295 HSS-Co Metal Drill Bit 2.0 x 49 mm

The Makita D-17295 HSS-Co metal drill bit is a precision-engineered tool designed for high-performance drilling in demanding metal applications. With a diameter of 2.0 mm and a total length of 49 mm, this bit is crafted from high-speed steel alloyed with 5% cobalt, providing superior heat resistance and structural integrity during intensive use. Its robust design ensures consistent results and long-lasting durability, making it a reliable choice for both professional metalworkers and dedicated DIY enthusiasts who require clean, accurate holes in hard materials.

Advantages

The primary benefit of this drill bit lies in its cobalt-alloyed composition, which significantly increases its hardness and resistance to thermal wear compared to standard HSS bits. This allows for efficient drilling in tough materials like stainless steel without premature dulling. The inclusion of a precision chisel edge ensures excellent centering and reduced wandering at the start of the drilling process. Furthermore, the cylindrical shank design provides universal compatibility with standard drill chucks, ensuring a secure grip and stable operation across a wide range of power tools.

Suitable for

• Drilling in stainless steel and alloyed metals
• General metalworking tasks
• Precision hole creation in hard steel
• Professional fabrication and repair projects
• DIY metal drilling applications

When it may not be suitable

This drill bit is specifically optimized for metal and stainless steel applications and may not be the most efficient choice for drilling in soft materials like wood or plastic, where standard high-speed steel bits might perform adequately. Additionally, due to its small 2.0 mm diameter, it is not intended for heavy-duty structural drilling or creating large-diameter holes.

Key specifications

• Material: HSS with 5% Cobalt
• Diameter: 2.0 mm
• Total length: 49 mm
• Shank type: Cylindrical
• Tip geometry: Chisel edge
• Application: Metal and stainless steel

How to use

To achieve the best results, ensure the drill bit is securely tightened in the chuck of your drill. Mark the center point of the hole to be drilled using a center punch to prevent the bit from slipping on the metal surface. Apply steady, moderate pressure while maintaining a consistent drilling speed. It is recommended to use a cutting oil or coolant during the process to reduce friction, dissipate heat, and extend the life of the drill bit, especially when working with stainless steel.

What to consider before purchase

• Verify that your drill chuck is compatible with a standard cylindrical shank.
• Ensure the 2.0 mm diameter meets the specific requirements of your project.
• Consider purchasing multiple bits if working on high-volume projects, as small-diameter bits are prone to breakage under excessive lateral force.

Usage recommendations

Always wear appropriate eye protection when drilling metal. Use a low to medium speed setting on your drill to prevent overheating and to maintain control over the drilling process.
