17/20 Caliber Piloted Flashhole Deburring Tool (Part #749004544)

Fast, clean, and repeatable flashhole removal for high‑performance assemblies.

Product Overview

The 17/20 Caliber Piloted Flashhole Deburring Tool is a purpose‑built solution for removing flashholes from precision‑machined components. Designed for both manual and CNC‑integrated operations, this tool delivers consistent, burr‑free results on a wide range of materials, including aluminum alloys, stainless steel, titanium, and high‑strength composites.

Standard Size: 17/20 mm (0.669 in) pilot diameter for rapid insertion and secure guidance.
Robust Construction: High‑speed steel (HSS) shank with a titanium‑nitride coating for extended tool life.
Optimized Geometry: Dual‑edge pilot design eliminates vibration and reduces cycle time.
Universal Compatibility: Fits most standard collet and chuck systems, making it ideal for CNC routers, drilling machines, and hand‑held power tools.
Safety‑Focused: Non‑splintering tip and ergonomic handle reduce operator fatigue.

Key Applications

This piloted flashhole deburring tool excels in demanding environments where precision and repeatability are non‑negotiable:

Aerospace structural components – wing skins, fuselage frames, and fastener holes.
Automotive engine blocks, transmission housings, and high‑performance chassis parts.
Medical device manufacturing – surgical instruments and implantable hardware.
Industrial tooling – molds, dies, and hydraulic cylinder housings.
Defense and aerospace research – prototype part preparation and testing rigs.

Benefits of Using the 17/20 Caliber Piloted Flashhole Deburring Tool

Reduced Cycle Times: The piloted design guides the tool directly into the flashhole, eliminating guesswork and speeding up production.
Consistent Quality: Uniform burr removal prevents re‑work, improves fit‑and‑finish, and maintains tight tolerances.
Extended Tool Life: TiN coating resists wear and heat, providing up to 30 % longer service intervals.
Operator Safety: The ergonomically balanced handle reduces hand strain and the non‑splintering tip minimizes chip ejection hazards.
Cost Efficiency: Lower scrap rates and fewer tool changes translate into measurable savings on high‑volume runs.

Installation & Use Instructions

Secure the tool in a compatible collet or chuck, ensuring the pilot is fully seated.
Set the machine’s spindle speed to a maximum of 12,000 rpm; adjust based on material hardness.
Apply a suitable cutting fluid to the workpiece to reduce heat buildup.
Position the tool directly over the flashhole and engage gently; the pilot will self‑center.
Maintain a steady feed rate; typically 0.5–1.0 mm per revolution for optimal burr removal.
After the operation, inspect the hole for cleanliness and repeat if necessary.

Frequently Asked Questions

Can this tool be used on hardened steel?: Yes. When paired with appropriate cutting fluid and a reduced RPM, the TiN‑coated shank handles hardened steel up to 45 HRC.
Is the tool compatible with CNC machines?: Absolutely. Its standard shank dimensions fit most CNC collet systems, and the pilot geometry provides repeatable positioning for automated cycles.
How often should the tool be inspected for wear?: We recommend a visual inspection after every 2,000 cycles or if you notice increased cutting forces. Replace the tip when the pilot edge shows visible rounding.
