Milwaukee hammer drills are renowned for their power, durability, and precision, but to maintain their peak performance, it’s crucial to use the right grease. This comprehensive guide delves into the technical specifications, usage, and maintenance of Milwaukee Hammer Drill Grease, ensuring your tool operates at its best for years to come.
What Type of Grease Should I Use for My Milwaukee Hammer Drill?
When it comes to lubricating your Milwaukee hammer drill, it’s essential to use the grease specifically recommended by the manufacturer. Milwaukee’s 49-08-5383 Hammer Bit Grease is the ideal choice for this purpose. This grease is designed to withstand the high-impact forces and extreme temperatures generated during hammer drilling operations.

Using the correct grease is crucial to prevent damage to your hammer drill’s internal components, such as the gears, bearings, and impact mechanism. Substituting with a non-recommended grease can lead to premature wear, reduced performance, and even tool failure.
How Often Should I Grease the Shank of My SDS Bits?
Regularly greasing the shank of your SDS (Slotted Drive System) bits is an essential maintenance practice for Milwaukee hammer drills. The SDS chuck mechanism relies on a tight fit between the bit and the chuck to transfer the high-impact forces efficiently. Over time, the SDS bit shank can become worn, leading to a loose fit and reduced performance.
To maintain optimal performance, it’s recommended to grease the SDS bit shank every 10-15 hours of use, or whenever you notice a decrease in drilling efficiency. This periodic greasing helps to reduce wear on the SDS chuck and ensures a secure, vibration-free connection between the bit and the tool.
When greasing the SDS bit shank, apply a thin, even layer of Milwaukee Hammer Bit Grease (49-08-5383) to the entire length of the shank. Avoid over-greasing, as this can lead to excess grease buildup and potential contamination of the work area.
Is it Normal for Grease to Leak from the Tip of My Milwaukee Hammer Drill During Heavy Use?
Grease leaking from the tip of your Milwaukee hammer drill is generally not a normal occurrence and may indicate an underlying issue. Excessive grease leakage can be caused by several factors, including:
- Faulty Seals: The hammer drill’s internal seals may be worn or damaged, allowing grease to escape from the tool’s housing.
- Excessive Grease Application: If too much grease is applied to the tool’s internal components, it can lead to leakage through the chuck or other openings.
- Extreme Operating Conditions: Prolonged use in high-impact, high-temperature, or dusty environments can cause the grease to break down more quickly, leading to leakage.
If you notice grease leaking from the tip of your Milwaukee hammer drill, it’s recommended to take the following steps:
- Clean the chuck and surrounding area with a clean, lint-free cloth or cotton swabs to remove any excess grease.
- Inspect the tool for any visible signs of seal damage or wear.
- If the issue persists, contact Milwaukee’s customer service or an authorized service center for further assistance. They may need to inspect the tool and replace any faulty seals or components.
Addressing grease leakage promptly is essential to maintain the tool’s performance and prevent further damage to the internal components.
Conclusion
Proper maintenance and the use of Milwaukee-recommended grease are crucial for ensuring the optimal performance and longevity of your Milwaukee hammer drill. By understanding the technical specifications, usage guidelines, and troubleshooting tips outlined in this comprehensive guide, you can keep your tool in top condition and tackle your toughest drilling projects with confidence.
