Description
The Irwin 1/4" Cobalt 135 Degree Jobber Length Drill Bit (63116) is a professional-grade tool crafted for demanding applications in metalworking. Built with a specialized M-35 High Speed Steel composition that includes a cobalt alloy, this drill bit is engineered to withstand the intense heat and abrasion generated when drilling into hard and difficult materials. Its advanced design focuses on performance and longevity, making it an essential tool for jobs involving stainless steel, hardened steel, and other tough alloys.
KEY FEATURES AND BENEFITS:
- Exceptional Durability: The M-35 High Speed Steel with a cobalt alloy provides superior resistance to heat and abrasion, extending the life of the drill bit when working with tough materials.
- Precision Drilling: The 135-degree split point is self-centering and starts on contact, preventing the bit from wandering and ensuring accurate hole placement without the need for a pilot hole.
- Efficient Performance: A heavy-duty web and spiral flute design allow for faster chip ejection, which helps to prevent clogging and reduce the heat generated during drilling.
- Reduced Torque: Shorter cutting lips decrease the amount of torque required to drill, making it easier to work with high tensile strength materials.
- Versatile Application: This drill bit is ideal for heavy-duty drilling tasks on a wide range of materials, including hardened steel, stainless steel, and titanium.
SPECIFICATIONS:
- Part Number: 63116
- Drill Size: 1/4 inch
- Overall Length: 4 inches
- Flute Length: 2-3/4 inches
- Drill Point Angle: 135 degrees
- Shank Type: Straight
HOW TO USE:
- Secure Your Material: Clamp the workpiece firmly to a workbench to prevent it from moving during drilling. This ensures safety and improves the accuracy of the hole.
- Select the Right Speed: Adjust your drill's speed to match the material. For harder metals, a slower speed is generally recommended to prevent overheating and premature wear on the bit.
- Apply Consistent Pressure: Apply steady, firm pressure to the drill as you begin. Let the bit's cutting edge do the work; excessive force can cause the bit to break.
- Use Lubricant: For optimal results and to prolong the life of the drill bit, apply a cutting fluid or lubricant to the drilling area, especially when working with stainless steel or other hard metals.
- Clear Chips: Periodically lift the bit from the hole to allow chips to eject. This prevents the hole from clogging and helps to cool the bit and workpiece.
BENEFITS OF USING IRWIN 1/4" COBALT 135 DEGREE JOBBER LENGTH DRILL BIT (63116):
- Enhanced Durability: The cobalt-enhanced steel construction ensures a longer tool life compared to standard HSS bits, particularly in high-temperature applications.
- Reduced Rework: The self-centering split point design results in more accurate holes from the start, minimizing the need for re-drilling or corrections.
- Time-Saving: Efficient chip ejection and the ability to start drilling without a pilot hole streamline the workflow and reduce overall project time.
- Cost-Effective: A longer-lasting bit means fewer replacements, providing better value over time, especially for frequent users.
- Versatile Performance: Effectively handles a variety of challenging materials, making it a go-to tool for a wide range of professional metalworking tasks.
FEATURES:
- Heavy-duty web construction
- Spiral flute design for fast chip removal
- M-35 high-speed steel with cobalt alloy
- Straight shank for standard chucks
- Jobber length for general purpose drilling
- Gold oxide finish for lubrication and reduced friction
- Designed for use on tough metals and abrasive alloys
