Best Titanium Countersinks in 2026

PREMIUM GRADE: KFD Killer Force Jobber Length Drill Bits are manufactured from M2 premium grade, high speed steel with a gold and black surface treated for use with stainless steel and other hard metal drilling

BEST USES: Can be used for most general use applications and compatible for multi material drilling with aluminum, iron, wood, plastic and stainless steel, offering a combination of hardness and toughness for wear resistance

HEAVY DUTY CUTTING: 135 degree split point for self-centering and fast precision drilling; Round shanks allow use with many tool holding systems; When run counterclockwise (right hand cut) spiral fluted tools evacuate chips to reduce clogging

HIGHER SPEED DRILL: Manufactured to National Aerospace Standard 907 and made of heat-resistant cobalt, these drill bits display higher red hardness which permits speeds up to 30% greater than high speed steel drills

BEST USES: The m35 5% cobalt drills are effective in drilling tough, high tensile strength materials such as Inconel, stainless steel and titanium, as well as wood, plastic and other hard metals

135 DEGREE CUTTING ANGLE: Jobber length drill bits have a 135 degree split point for self-centering, fast penetration, and drilling with precision

COMPATIBILITY – 1/4” round shank fits all handheld and stationary drills.

【Multiple Sizes Countersink Drill Bit】 – The countersink drill bit set is machined from high speed steel and come in 5 most popular sizes : 1/4, 3/8, 1/2, 5/8, 3/4 inch, which will meet your daily needs.

【HSS Countersink Drill Bit】– The countersink drill bit is made of High-Speed Steel with Titanium Coating, and 82-degree tips for drilling into wood, soft metals, rubber, plastic, mild steel, don't work on stainless.

【Universal 1/4”Hex Shank】– The countersink drill bit is designed with 1/4" round shank, which fits all handheld and stationary drills. And Five-flute design reduces vibration and removes chip better, provides smoother drilling experience and extended bit life.

M35 Cobalt HSS: Super tough, resistant to wear, high thermal threshold. Designed for tackling tough materials like stainless steel and other high-performance alloys. Please ensure sufficient lubrication and cooling in extensive uses.

Cobalt coating helps with wear and thermal. Please be reminded that the countersinking performance will not be impacted even if coatings are worn down. The wear and tear of coating is normal and the performance relies on hardness of the countersink bit itself.

PRO compatibility for professional machinist and DIY enthusiasts: Round shank can be fitted with hand drills and bench drills. We recommend using bench drills for optimal results when working with hard alloys.

HSS Material:This countersink bit is crafted from industrial - grade M35 cobalt HSS, which is harder,more wear-resistant,and more durable than regular HSS,providing better control and stability.

Product Size: Round shank uses the most common drill bits on the market. 90 degree angle, 0.39'' inch round shank,0.8'' inch body diameter, countersinks 10 - 15 mm, Better results on the drill.

TIAN Coating:Aluminum titanium nitride coating with 35Gpa nano-hardness ensures better performance on hard metals, allowing for higher speeds.800℃ max working temperature gives it an extra long service life.

M35 Cobalt HSS: Super tough, resistant to wear, high thermal threshold. Designed for tackling tough materials like stainless steel and other high-performance alloys. Please ensure sufficient lubrication and cooling in extensive uses.

TiAlN coating, 35Gpa nano hardness and 800 celsius thermal capability. Please be reminded that the countersinking performance will not be impacted even if coatings are worn down. The wear and tear of coating is normal and the performance relies on hardness of the countersink bit itself.

PRO compatibility for professional machinist and DIY enthusiasts: Round shank can be fitted with hand drills and bench drills. We recommend using bench drills for optimal results when working with hard alloys.
