Titan Usa CD44729 Jobber Drill Bit No. 30 Hss 135 Deg

Product Description

The TITAN USA CD44729 is a No. 30 wire-size jobber-length drill bit engineered for general-purpose drilling in ferrous and non-ferrous metals. It measures 0.1360 inches in diameter and carries a 135-degree split-point geometry that reduces walking and allows drilling to start without a center punch. The bit is manufactured from high-speed steel with a black oxide, oxide, and gold combination coating that improves lubricity and extends tool life in production drilling environments. Overall length is 2.875 inches with a 1.75-inch spiral flute and a straight cylindrical shank. Right-hand cutting direction and a regular spiral make it compatible with standard drill chucks and magnetic-base drills.

This jobber drill is suited for shop, field, and maintenance drilling applications across a wide range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is a common choice for electricians, plumbers, HVAC technicians, and general tradespeople who need a compact, reliable drill bit for metal-on-metal work. The 13xD flute-to-diameter ratio provides adequate chip evacuation for through-hole and blind-hole applications up to 1.75 inches deep.

Key Features

• 135-degree split-point tip reduces drill walk and eliminates the need for center-punching on flat surfaces
• High-speed steel construction withstands heat generated during cutting in steel, stainless steel, and superalloys
• Black oxide, oxide, and gold combination coating reduces friction and improves chip flow
• Right-hand spiral flute with 1.75-inch flute length supports maximum drilling depth of 1.75 inches
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters
• Two-flute, regular spiral design keeps the bit balanced and easy to resharpen

Compatibility

Designed as a standard jobber-length drill bit compatible with any drill press, handheld power drill, or magnetic-base drill fitted with a chuck sized to accept a 0.1360-inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified tradesperson familiar with rotary cutting tools and safe drilling practices. Secure the workpiece firmly before drilling and confirm the chuck is tightened on the shank before starting the tool. Use appropriate cutting fluid or lubricant when drilling steel or stainless steel to reduce heat buildup and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
